SUMMARY:Seminar: ‘The Hunt for Multiple Axions’
DESCRIPTION:Title: ‘The Hunt for Multiple Axions’ \nSpeaker: Arturo de Giorgi (University of Durham). \nVenue&Time: Red Room / 15:00 \nAbstract: Axions and axion-like particles may arise in Nature as a spectrum rather than as a single field. Such a scenario naturally emerges in string-inspired constructions\, as well as in reasonably simple bottom-up extensions of single axion models. In such multi-axion scenarios\, new signal features arise\, and recasting of existing experimental bounds from single-axion constraints becomes generally non-trivial. This motivates a closer look at how laboratory axion searches are impacted when multiple states contribute. In this talk\, I will first briefly introduce bulk axions in extra dimensions as a concrete framework that naturally generates multiple modes\, and highlight some of the phenomenological subtleties that follow. I will then present general results for multi-axions–photon oscillations\, showing how coherence and interference can either enhance or suppress signals\,  with direct implications for light-shining-through-a-wall experiments and beyond.

SUMMARY:Seminar: 'Sub-GeV Dark Matter\, Neutrino Masses\, and Astrophysical Signals from a Rich Dark Sector'
DESCRIPTION:Title: ‘Sub-GeV Dark Matter\, Neutrino Masses\, and Astrophysical Signals from a Rich Dark Sector.’ \nSpeaker: Elina Merkel (University of Bologna) \nVenue&Time: Red Room / 15:00 \nAbstract: Rich dark sectors provide an attractive framework for addressing several puzzles in particle physics and cosmology within a single model. In this talk\, I will present a simple sub-GeV dark-sector realization featuring a dark matter candidate\, a light scalar mediator\, and an extended neutrino sector. I will show how the model can reproduce the observed relic abundance\, generate light neutrino masses\, and satisfy cosmological constraints. I will then discuss its phenomenological implications\, focusing on neutrino signals that could be probed by current and future neutrino telescopes.

SUMMARY:Seminar: 'NLO Running in the SMEFT'
DESCRIPTION:Title: ‘NLO Running in the SMEFT’ \nSpeaker: Lukas Born (University of Bern). \nVenue&Time: Red Room / 15:00 \nAbstract: The Standard Model Effective Field Theory (SMEFT) provides a systematic framework for parameterizing heavy new physics in a model-independent way. A central ingredient for precision analyses within this framework is the renormalization group equations (RGEs)\, governing the running of the Wilson coefficients across energy scales. Our recent computation of the two-loop β-functions in the SMEFT marks a milestone in this program\, opening the door to genuine next-to-leading order (NLO) analyses. \nIn this talk\, I will first discuss the key technical challenges we encountered in our calculation\, how we addressed them by modifying the Warsaw basis\, and the consistency checks on our results. Second\, I will turn to a concrete phenomenological application\, demonstrating that NLO running effects play an important role in Electroweak Precision Observables (EWPO).

SUMMARY:Seminar: 'Differential observables for the Higgs-strahlung process to all orders in EFT'
DESCRIPTION:Title: ‘Differential observables for the Higgs-strahlung process to all orders in EFT.’ \nSpeaker: Sourav Bera from Tata Institute of Fundamental Research (TIFR) \nVenue&Time: Red Room / 15:00 \nAbstract: We develop methods to obtain the fully differential cross-section for the  f f \to Z(ll) h  process to any desired order in  effective field theory (EFT). To achieve this\, we first derive a mapping between the partial wave expansion and the EFT expansion  to all orders. We find that at lower orders\,  EFT predicts correlations between the different partial wave coefficients. This allows us to construct linear combinations of partial wave coefficients that get their leading contributions from a higher dimension EFT operator. We then introduce experimental observables\, the so called angular moments — that   probe these  linear combinations of partial wave coefficients — and can be determined from a fully differential analysis of the angular distribution of the leptons arising from the Z – decay. We show that  analysing the dependence of these angular moments on the Zh invariant mass allows us to systematically probe all higher dimension EFT operators contributing to this process. In particular\, we discuss how our results can be used to probe dimension-8 operators  in the Standard Model EFT (SMEFT). While we take  the Higgs-strahlung process as an example\, the methods developed here are completely general and can also be applied to other 2-to-2 collider processes.

SUMMARY:Seminar: 'A hot take on electroweak skyrmions'
DESCRIPTION:Title: ‘A hot take on electroweak skyrmions’ \nSpeaker: Luis Gil (Universidad de Granada). \nVenue&Time: Red Room / 15:00 \nAbstract: Skyrmions are stable and topologically non-trivial field configurations that behave like localized particles. They appear in the chiral  effective theory for pions\, where they correspond to the baryon states\, and might also exist in the electroweak theory\, in the presence of certain effective interactions.\nIn this talk\, focusing on toy models that capture different limits of the electroweak sector of the Standard Model (SM)\, we will how skyrmions not classically stable at zero temperature can be stabilized by thermal effects. This motivates the study of skyrmions in the quantum effective action of the SM\, where they might constitute a dark matter candidate without new physics.

SUMMARY:Seminar: 'Revisiting Critical Higgs Inflation: CMB Observables\, Electroweak Couplings\, and Perturbative Unitarity'
DESCRIPTION:Title: Revisiting Critical Higgs Inflation: CMB Observables\, Electroweak Couplings\, and Perturbative Unitarity\n \nSpeaker: Sarah R. Geller (Yale U.) \nVenue & Time: Red Room / 15:00\n\n\n\nAbstract:\nAn intriguing and economical possibility to explain many cosmological observations is Higgs inflation\, in which inflation is driven by the Standard Model Higgs with a non-minimal coupling to gravity. I will discuss near-critical Higgs inflation at two loops and show that\, for any set of parameters derived from SM couplings at the electroweak scale and run to the inflationary scale\, one can find a value of the non-minimal coupling that brings the model into compliance with all measured CMB observables. Unlike standard Higgs inflation\, which typically requires unnaturally large values of the non-minimal coupling\, I will demonstrate that in metric gravity we can match the CMB while staying within 3σ of electroweak precision data with non-minimal couplings on the order of 50–200. The success of the model\, however\, comes at the cost of self-consistency when it is treated as an effective description of electroweak-scale physics; that is\, the model becomes unavoidably sensitive to physics beyond the SM in the UV\, undermining the simplicity that originally motivated Higgs inflation.

SUMMARY:A diffuse flux of MeV ALPs
DESCRIPTION:Title: ‘A diffuse flux of MeV ALPs’ \nSpeaker: Marina Cermeño \nVenue&Time: Red Room / 15:00 \nAbstract: MeV scale axion-like particles can be produced with semi-relativistic velocities in Galactic supernovae\, leading to a diffuse flux that can be detectable in neutrino water-Cherenkov detectors (Super + HyperK).

SUMMARY:Seminar: 'Classical Krylov probes and chaotic semiclassical strings'
DESCRIPTION:Title: ‘Classical Krylov probes and chaotic semiclassical strings’ \nSpeaker: Saskia Demulder (CUNEF) \nVenue&Time: Red Room / 15:00 \nAbstract: Quantum chaos is a central theme in string theory\, but classical chaos is also a generic feature of semiclassical string dynamics. Motivated by the need to explore the broad landscape of non-integrable string dynamics\, I will introduce a classical version of Krylov complexity and related diagnostics using the Koopman-von Neumann formulation of classical mechanics. I will then explain how this framework can be applied to integrability-breaking deformations of otherwise integrable semiclassical string solutions. In particular\, I will show how such deformations induce characteristic redistributions of spectral weight\, leading to observable-dependent delocalisation and spreading in Koopman-Krylov space. This talk is based on [2602.23421] and ongoing work\, both in collaboration with Rathindra N. Das.

SUMMARY:Seminar by Marco Finetti (U. Aveiro)
DESCRIPTION:Title: ‘First Order Phase Transitions and Gravitational Waves’ \nVenue&Time: Red Room / 15:00 \nSpeaker: Marco Finetti (U. Aveiro) \nAbstract: The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave (GW) detector\, opening a new observational window for both astrophysics and early-Universe cosmology. Operating in the millihertz band\, it will probe a rich superposition of GW signals. Astrophysical population models predict a sufficient number of signals in the LISA band to blend together and form an irresolvable Galactic foreground noise. In addition\, a stochastic gravitational wave background (SGWB) of cosmological origin could add an unknown component to the measured noise. In this talk\, I will assess the bias induced on the parameter estimation of stochastic signals\, arising from the unresolved binaries buried within the cosmological signal. Using a representative SGWB model\, I will quantify the impact of this effect on the reconstruction of the foreground template parameters and\, most importantly\, on those of the SGWB model itself. Neglecting inter-template correlations can lead to significan biases\, and\, for several benchmark cases\, those biases exceed the statistical reconstruction uncertainties. These findings expose a key limitation of existing template-based strategies and indicate that unbiased component separation will likely require additional information\, such as constraints from resolved sources obtained through global-fit analyses.

SUMMARY:Seminar: 'Weak Particles with a strong impact'
DESCRIPTION:Title: ‘Weak Particles with a strong impact’ \nSpeaker: Aritra Gupta (Krea University\, India) \nVenue&Time: Red Room / 15:00 \nAbstract: Dark matter and neutrinos are among the most elusive particles in nature\, yet they play a central role in the evolution of the Universe. Their extremely weak interactions make them difficult to detect\, but also allow them to probe environments inaccessible to ordinary matter. \nIn this colloquium\, I will discuss how astrophysical systems and neutrino observatories can be used to explore the physics of dark matter and neutrinos beyond the Standard Model. I will present scenarios where dark matter and neutrino physics are intimately connected\, leading to observable consequences in cosmology and astroparticle experiments. I will also discuss how dark matter accumulated inside compact stellar environments can significantly modify supernova cooling along with other detectable indirect signatures. Throughout the talk\, I will highlight how compact stars\, neutrino detectors\, and astrophysical observations together provide new windows into the dark sector.

SUMMARY:Seminar: 'On the evidence for elastic interactions in the dark sector'
DESCRIPTION:Title: ‘On the evidence for elastic interactions in the dark sector’ \nSpeaker: Jose Beltrán Jiménez\, University of Salamanca. \nVenue & Time: Red Room / 15:00 \nAbstract: The increasing quality of cosmological data has revealed > some tensions among different probes that could be signalling the necessity of incorporating new physics into our cosmological model. One particularly intriguing possibility is the existence of elastic interactions between dark matter and dark energy. Not only do these interactions provide a natural mechanism to relief cosmological tensions\, but there is also compelling observational evidence for them\, to the extent that a detection could even be claimed. I wil review the potential of these scenarios in relation to the cosmological tensions and discuss distinctive signatures that can be probed with future data\, thus providing a smoking gun for these interactions.

SUMMARY:Seminar: 'Perturbative aspect of electroweak phase transitions in the Early Universe'
DESCRIPTION:Title: ‘Perturbative aspect of electroweak phase transitions in the Early Universe’\n\n\n\nSpeaker: Andrii Dashko (DESY)\n\n\nVenue&Time: Blue Room / 12:00\n\n\nAbstract: We present a study of the perturbative description of thermally driven electroweak phase transitions (EWPT) in the early universe. Focusing on strong first-order transitions\, which are relevant for gravitational wave cosmology\, we examine the dimensional reduction as a tool for a precise and systematic description focusing on the running of effective parameters within the effective field theory (EFT)\, and the impact of higher-dimensional operators. This allows us to assess the range of validity and theoretical uncertainties of the EFT approach. We demonstrate these results with applications to the Standard Model Effective Field Theory (SMEFT) and singlet extensions of the Standard Model\, both of which can realize strong EWPT.

SUMMARY:Seminar: 'Primordial Black Holes -- Positivist Perspective\, Quantum Quiddity and Galaxy Genesis'
DESCRIPTION:Title: ‘Primordial Black Holes — Positivist Perspective\, Quantum Quiddity and Galaxy Genesis’ \nSpeaker: Florian Kühnel\, (TU Dortmund & LMU Munich) \nVenue&Time: Red Room / 15:00 \nAbstract: Primordial black holes are black holes that may have formed in the early Universe. Their masses potentially span a range from as low as the Planck mass up to many orders of magnitude above the solar mass. This\, in particular\, includes those black holes recently discovered through gravitational waves\, and (part of) these may conceivably be of primordial origin. After a general introduction on primordial black holes\, I review the observational hints for their existence — from a variety of lensing\, dynamical\, accretion and gravitational-wave effects. As I will show\, all of these (over 20) may be explained by a single and simple unified model\, naturally shaped by the thermal history of the Universe. If time permits\, I discuss how recent advances in our understanding of quantum effects in black holes impact PBHs. This prominently concerns deviations from Hawking radiation in the form of the memory-burden effect. Finally\, I will elucidate on the role primordial black holes have on early galaxy and star formation.

SUMMARY:Seminar by Christian Northe (Institute of Physics\, Prague)
DESCRIPTION:Title: Entanglement through topological interfaces in CFT revisited \nSpeaker: Christian Northe (Institute of Physics\, Prague) \nVenue&Time: Red Room / 15:00 \nAbstract: Present theoretical predictions for the entanglement entropy through topological defects are violated in numerical simulations of critical systems. In this talk\, I discuss a paradigm shift in the preparation of reduced density matrices in the presence of topological defects\, and emphasize the role of defect networks with which they can be dressed. Grouplike and duality defects are considered in detail for the Ising model\, establishing agreement with all numerically found entanglement entropies. Since this new construction functions at the level of reduced density matrices\, it accounts for topological defects beyond the entanglement entropy to other entanglement measures. The framework employs boundary conformal field theory techniques to implement the factorization of Hilbert space\, which I recapitulate at the beginning of the talk and discuss its relation with the entanglement spectrum.

SUMMARY:Seminar: 'Gravitational waves from phase transitions in the early Universe: sound waves and MHD turbulence'
DESCRIPTION:Title: Gravitational waves from phase transitions in the early Universe: sound waves and MHD turbulence \nSpeaker: Alberto Roper Pol (Geneva) \nVenue&Time: Red Room / 15:00 \nAbstract:  Gravitational waves (GWs) can be produced by a first-order phase transition in the early Universe via the fluid perturbations induced in the primordial plasma by the expansion and collision of broken-phase bubbles. I will review the production of GWs by the anisotropic stresses of velocity and magnetic fields induced in a first-order phase transition and present recent developments on the analytical estimates and numerical simulations that address the stochastic GW background produced by acoustic motion (sound waves) and magnetohydrodynamic (MHD) turbulence. These GWs could be detectable by current and future GW detectors like LISA or PTA\, potentially providing us with direct clean information of the physics at the high energies of the early Universe and probing beyond the Standard Model physics. In addition\, the presence of magnetic fields at a phase transition leads to coupled non-linear fluid perturbations\, described by MHD turbulence\, that will impact the cosmological GW background. The study of these effects can be used to put constraints on primordial magnetic fields. These fields would evolve until present time and leave observable imprints in\, for example\, the CMB and in the cosmic voids of the large-scale structure of the Universe\, allowing us to combine GW observations with other cosmological and astrophysical observations in a multi-messenger approach.

DESCRIPTION:Title: Quantum computing for lattice gauge theories: from the Schwinger model to an SO(3) Quantum Link model \nSpeaker: Bipasha Chakraborty (University of Southampton) \nVenue&Time: Red Room / 15:00 \nAbstract: Quantum computing provides a promising framework for simulating strongly coupled gauge theories relevant to high-energy physics. In this talk\, I will discuss quantum simulations of lattice gauge theories\, focusing on the Schwinger model as a benchmark Abelian system and on a non-Abelian SO(3) gauge theory formulated as a quantum link model. I will outline gauge-invariant encodings and circuit implementations suitable for near-term devices\, and comment on prospects for using quantum algorithms to study real-time dynamics and other regimes challenging for classical methods.

SUMMARY:Seminar: 'Collective vortex dynamics in strongly coupled superfluids'
DESCRIPTION:Title: Collective vortex dynamics in strongly coupled superfluids \nSpeaker: Mikel Sanchez-Garitaonandia (University College Dublin) \nVenue&Time: Red Room / 15:00 \n\nAbstract: Vorticity appears across a wide range of fluid phenomena\, from the dynamics of classical fluids to quantum vortices in superfluids. In the latter case\, vortices are topological defects that interact both with each other and with the surrounding medium. When a large number of vortices are present\, it is natural to ask whether their collective behaviour can itself be described as a fluid\, captured by an effective theory of vortex hydrodynamics. In this talk\, I will explore the dynamics of many vortices in a strongly coupled superfluid with holography. By performing real-time simulations\, I will investigate how the system approaches equilibrium and how its macroscopic behaviour compares with the predictions of vortex hydrodynamics. This allows to assess the range of validity of the hydrodynamic description and to understand how the system behaves beyond it.

SUMMARY:Seminar by Maria Olalla Olea Romacho (King's College\, London)
DESCRIPTION:Title: ‘Traces from Primordial Magnetogenesis’ \n  \nSpeaker: Maria Olalla Olea Romacho (King’s College\, London) \n  \nVenue&Time: Red Room / 15:00 \n\nAbstract: Magnetic fields permeate the Universe across a wide range of scales\, from galaxies and clusters to the most underdense regions of the cosmic web. Gamma-ray observations of TeV blazars suggest the presence of magnetic fields in intergalactic voids\, where no efficient late-time astrophysical sources exist\, pointing toward a possible primordial origin and a direct link to early-Universe physics. Primordial magnetic fields arise naturally in scenarios such as inflation or cosmological phase transitions. In this seminar\, I present a multi-messenger perspective on their observational signatures. On the particle physics side\, I discuss collider-motivated models of electroweak phase transitions\, highlighting connections to blazar observations and stochastic gravitational-wave backgrounds. On the astrophysical side\, I show how primordial magnetic fields enhance small-scale structure formation\, leading to dense dark matter minihalos that boost indirect detection signals\, and how they impact high-redshift observables probed by the James Webb Space Telescope.

SUMMARY:Madrid's Polygonal Gravity Seminar Series
DESCRIPTION:Venue&Time: Red Room / 11:30 / 15:00 \nPROGRAM: \n——————— \n11:00 Welcome coffee \n——————— \n11:30h     First Talk \nSpeaker: Jelle Hartong (Edinburgh U.) \nTitle: The Geometry of Gravitational Radiation \nAbstract: This talk concerns asymptotically flat vacuum solutions of GR in\n4 spacetime dimensions. The asymptotics of such metrics is quite intricate\nand depends on how we approach infinity. If we follow null geodesics we\nend up at future null infinity. This is where massless fields\, including\ngravitational radiation ends up. In this talk we will study the metric\nnear future null infinity with an emphasis on geometrical structures that\nemerge in that part of the spacetime. \nFuture null infinity of an asymptotically flat spacetime is a conformal\nCarroll manifold. I will not assume any familiarity with Carroll geometry\nand explain the relevant geometrical notions as we go along. We will\nconsider asymptotic solutions to the 4D vacuum Einstein equations where\nfuture null infinity is endowed with the most general Carroll metric data\nthat is allowed by the Einstein equations. This can be used to define an\nenergy-momentum tensor (EMT) at future null infinity by varying a suitably\nrenormalised action with respect to the boundary Carroll metric data. It\nis shown that the Ward identities obeyed by this boundary EMT agree with\nthe Bondi loss equations that describe the loss of energy and momentum due\nto the emission of gravitational waves. The metric near future null\ninfinity can be formulated in terms of a Cartan geometry based on the\nconformal Carroll algebra. The non-vanishing curvatures of said algebra\ndictate how radiative the spacetime is. For example\, the vacuum degeneracy\nis described by a flat conformal Carroll connection. We will see that the\nBondi loss equations can be rewritten as flux-balance laws where the\nfluxes are determined by the Cartan geometry for the conformal Carroll\nalgebra. \n——————– \n15:00h     Second Talk \nSpeaker: Eric A. Bergshoeff (U. of Groningen) \nTitle: Massive gravity in the lab \nAbstract: In this talk I will discuss a connection between the so-called\nchiral massive GMP spin-2 mode in the Fractional Quantum Hall effect and a\nthree-dimensional (one time and two space) relativistic massive spin-2\nfield in quantum field theory. In particular\, I will show how the spin-2\nGMP mode follows by taking a special non-relativistic limit of linearized\nthree-dimensional massive gravity which are the planar Fierz-Pauli\nequations. I will discuss how these results can be generalized to integer\nhigher-spins and will present results for half-integer spins as well. \n——————– \n16:15  Farewell coffee \n—————————————————————————– \nMore information about these and following monthly seminars can be found at the\nwebpage \nhttps://sites.google.com/view/polygrav \nWe very much hope to see you there!

SUMMARY:Seminar by Isaac Tutusaus (ICE\, Barcelona)
DESCRIPTION:Title: Probe combination to constrain cosmology in Euclid \nSpeaker: Isaac Tutusaus (ICE\, Barcelona) \nVenue&Time: Red Room / 15:00 \nAbstract: Following its successful launch in July 2023 and the start of its scientific survey in February 2024\, Euclid has become the first stage-IV photometric survey in operations. In addition to its photometric observations\, Euclid is also conducting a spectroscopic survey\, which allows us to add even more probes to a combined analysis from Euclid data alone. In this talk I will present the forecasts for a combined analysis at the end of the mission\, focusing in particular on how combining multiple probes helps break parameter degeneracies and leads to tighter constraints on the cosmological model under investigation. I will conclude by outlining current efforts toward a combined analysis with Euclid’s first data release.

SUMMARY:Seminar: 'Symmetry TFTs for Continuous Spacetime Symmetries'
DESCRIPTION:Title: Symmetry TFTs for Continuous Spacetime Symmetries \nSpeaker: Iñaki Garcia Etxebarria (Durham U.) \nVenue & Time: Red Room / 3:00 PM \nAbstract: I will discuss our recent proposal for the Symmetry Topological Field Theory (SymTFT) for global\, continuous spacetime symmetries ( https://arxiv.org/abs/2509.07965 ). For a d-dimensional theory\, it is given by a (d + 1)-dimensional BF-theory for the spacetime symmetry group\, and whenever d is even\, it includes also Chern-Simons couplings\, that encode conformal and gravitational anomalies. This proposal is supported by the similarity to two- dimensional Jackiw-Teitelboim gravity in the d = 1 case and the topological limit of four-dimensional gravity in the d = 3 case. I will discuss how topological defects constructed from this SymTFT act by applying the associated spacetime symmetry transformation. Finally\, I will discuss the relation to gravity and holography.

SUMMARY:Seminar: 'EFTs for BSM: Counting\, Ambiguities\, and Application'
DESCRIPTION:Title: ‘EFTs for BSM: Counting\, Ambiguities\, and Application’\n\n\nSpeaker: Shakeel Ur Rahaman (IPPP Durham).\n\n\nVenue&Time: Red Room / 15:00 \nAbstract: The two principal frameworks for modeling the Beyond Standard Model physics as an Effective Field Theory (EFT) are the Standard Model EFT (SMEFT) and the Higgs Effective Field Theory (HEFT). SMEFT is constructed in the electroweak symmetric phase\, inherently utilizing the Higgs doublet\, whereas HEFT is defined in the broken phase using the physical Higgs boson alongside a separate set of Goldstone bosons. The unavoidable necessity of truncating these effective field theory expansions creates technical ambiguities that are fundamentally interwoven with the redundancies inherent in general field redefinitions. In this talk regarding HEFT\, the focus will be primarily on its methodology for building operators\, its power counting scheme\, and the associated truncation uncertainties. These properties are already well-established within the SMEFT framework. For SMEFT\, the discussion will center on its application in precision calculations and its practical implementation in Monte Carlo event generators such as Sherpa.

SUMMARY:Seminar: 'Observing Quantum Gravity in Extremely Cold Horizons'
DESCRIPTION:Title: ‘Observing Quantum Gravity in Extremely Cold Horizons’ \nSpeaker: Roberto Emparan (Universidad de Barcelona) \nVenue&Time: Red Room / 15:00 \nAbstract: Recent developments have revealed that black holes near extremality exhibit large quantum fluctuations in their geometry\, marking a controllable breakdown of semiclassical quantum field theory in curved spacetime. In this talk\, I will discuss how these fluctuations can be revealed through scattering waves off the black hole. In particular\, we find that extremely cold black holes become transparent to low-frequency light or gravitational radiation. Although such signatures are extraordinarily hard to detect\, they provide concrete signatures of quantum gravity at play in near-extremal regimes.

SUMMARY:Seminar: 'Beyond the Minimal Axion: Robustness of Standard Predictions'
DESCRIPTION:Title: ‘Beyond the Minimal Axion: Robustness of Standard Predictions’ \nSpeaker: Sung Mook Lee (CERN) \nVenue & Time: Red Room / 15:00 \nAbstract: The QCD axion is one of the most compelling candidates for physics beyond the Standard Model\, as it can simultaneously solve the strong CP problem and account for the dark matter abundance. In the minimal single-axion framework\, especially in a post-inflationary cosmology\, the combination of axion gauge coupling quantization and axion production from string networks leads to sharp and highly predictive targets. In this talk\, we revisit these predictions in a simple but realistic setup with an additional confining dark gauge group and extra axion degrees of freedom. We will show how axion mixing and defect dynamics can modify both the coupling predictions and the relic abundance expectations through emergent features specific to multi axion scenarios\, and discuss when the standard single axion benchmarks remain reliable. This provides a useful test of what remains truly robust in extended axion theories and helps guide current experimental targets.

SUMMARY:Seminar: 'How string theory computes quantum gravity amplitudes'
DESCRIPTION:Title: ‘How string theory computes quantum gravity amplitudes’ \nSpeaker: Lorenz Eberhardt (U. Amsterdam) \nVenue&Time: Red Room / 15:00 \nAbstract: String theory provides a framework in which quantum gravitational scattering amplitudes are ultraviolet finite and computable in perturbation theory. These amplitudes are defined by integrating over the moduli space of Riemann surfaces\, replacing the Feynman diagram expansion of field theory by a sum over worldsheet topologies. I will review how this definition arises and explain structural properties such as UV-finiteness\, dual resonance and their Regge behavior. I will then discuss recent progress in explicit computations\, focusing on one-loop amplitudes and new results on their high-energy behavior.

SUMMARY:Seminar: 'Cosmological Magnetic Fields from Ultralight Dark Matter'
DESCRIPTION:Title: Cosmological Magnetic Fields from Ultralight Dark Matter \nSpeaker: Robert Brandenberger (McGill) \nVenue&Time: Red Room / 15:00 \nAbstract: A coherently oscillating ultralight dark matter field which couples to electromagnetism in the same way as an axion induces a tachyonic instability which leads to the generation of cosmological magnetic fields immediately after the time of recombination. The mechanism also opens up channels which can facilitate the formation of supermassive black holes.
