SUMMARY:SPS Journal Club: 'Probing the Rigidity of String Theory'
DESCRIPTION:Speaker: Georgina Staudt (Max Planck Institute Munich) \n\nVenue&Time: Red Room / 12:00 \n\nAbstract: We investigate the deformability of the Veneziano amplitude. If string theory is the unique theory of quantum gravity\, the tree level amplitudes of weak coupling limits should be non-deformable. We make progress in this direction for tachyon-free superstring theories by deriving a general positivity bound and excluding some specific families of deformations.

SUMMARY:Holo Club: Explicit Connections Between Krylov and Nielsen Complexity
DESCRIPTION:Speaker: Le-Chen Qu (IFT) \n\nVenue&Time: Grey Room 3 / 11:30 \n\nAbstract: We establish a precise correspondence between Krylov complexity and Nielsen complexity in quantum many-body systems. By identifying the Krylov basis with the generators of elementary gates in Nielsen’s geometric framework\, the Krylov complexity of precursor operators acquires a geometric interpretation as the length of straight-line paths in Nielsen geometry. This construction provides an upper bound on Nielsen complexity\, which becomes exact in the small-precursor limit. Employing the SYK model as a test case\, we demonstrate that the straight-line trajectory satisfies the Nielsen geodesic equation and remains both locally and globally minimizing up to a critical value of $z$\, beyond which conjugate points and geodesic loops arise. Within this framework\, cost functions quadratic in the Krylov index are further shown to reproduce the conjectured proportionality between the complexity growth rate and the operator size.

SUMMARY:Searching for New Physics through the Neutrino (bag)pipe
DESCRIPTION:Daniel Naredo Tuero PhD dissertation \n\nSearching for New Physics through the Neutrino (bag)pipe \n\nVenue&Time: Red Room / 11:00 \n\nAbstract:\nAmong the many open problems that plague the Standard Model (SM) of particle physics\, the massive nature of neutrinos stands out as it is one of the few indications of New Physics that we have observed in our terrestrial laboratories\, as supported by the phenomenon of neutrino flavour oscillations. Neutrinos offer a rich phenomenological and complementary programme\, from laboratory signals to cosmological imprints\, as we will explore in this Thesis. First\, we will assess the status of the cosmological neutrino mass bound in light of the latest results from DESI\, identifying the features and tensions in the data that are driving this ever-tightening constraint. Second\, we will consider the inclusion of heavy Majorana right-handed neutrinos\, the most economical SM extension to generate neutrino masses. In particular\, we will show how it is possible to constrain heavy neutrinos above the electroweak scale by harnessing their effects on precision observables. Lastly\, we will investigate the role of neutrino data in the global fit of the SM Effective Field Theory (SMEFT)\, showing that the inclusion of neutrino oscillation and scattering data can add new valuable information. \nSupervisores: Enrique Fernández-Martínez y Xabier Marcano

SUMMARY:Large neutrino mass in cosmology and keV sterile neutrino dark matter from a dark sector
DESCRIPTION:Speaker: Thomas Schwetz from Karlsruhe Institute of Technology (KIT)\n\n\n\n\n\nVenue&Time: Red Room / 3:00 PM \n\nAbstract:\nRecent results from cosmology place sever upper bounds on the sum of neutrino masses\, starting to be in conflict with lower bounds from neutrino oscillations. If this neutrino tension persists\, it may indicate new physics in cosmology and/or neutrino physics. After a brief review of the present state\, I discuss a new physics scenario able to explain this tension. It is based on an extended seesaw model for neutrino mass\, including a number of massless neutrinos acting as dark radiation\, as well as a keV state as a dark matter candidate. The dark sector is brought into equilibrium with neutrinos between BBN and recombination. This scenario predicts a slight increase in the effective number of neutrino species Neff at recombination\, potentially detectable byfuture CMB missions.

SUMMARY:SPS Journal Club: Symmetric Moduli Spaces\, the Swampland Distance Conjecture (...and the Emergent String Conjecture?)
DESCRIPTION:Speaker: Bernardo Fraiman (IFT)\n\n\nVenue&Time: Red Room / 12:00\n\n\nAbstract: For non-compact\, locally symmetric moduli spaces M\, the set of geodesics and the geometry of the boundary can be completely characterised using group theory. Under the assumption that M is “compactifiable” and some mild conditions on the spectrum of states\, we prove the SDC for all locally symmetric spaces. We show that the states necessarily transform in some representation of the local isometry group\, and that the convex hull encoding the exponential rate at which the leading tower of states becomes light coincides with the convex hull of the weights of the representation.\n\nIn this talk I will discuss briefly some aspects of the proof\, the domain of applicability of our assumptions and their limitations. If time permits\, I will also explain how the relation between towers and weights allows one to classify moduli spaces\, particle state representations and space time dimensions compatible with the Emergent String Conjecture. Based on 2508.18401 and work in progress.

SUMMARY:Dragon School: cosmic-ray theory\, phenomenology and beyond
DESCRIPTION:This school is intended to provide an overview about a variety of topic centered around the problem of cosmic-ray transport in the Galaxy and non-thermal diffuse emissions. We will provide both dedicated seminars and hands-on sessions on the modeling and computation of cosmic-ray propagation and the correlated non-thermal emissions in different astrophysical environments. In particular\, the event will feature a detailed presentation of the state-of-the-art theoretical and numerical tools to calculate relevant astro-particle quantities (production of gamma-ray\, radio or neutrino emission\, as well as the signals produced by dark matter)\, especially focused on the broad applicability of the DRAGON2 code. \nThis event will be held at the Institute of Theoretical Physics in Madrid (Spain) from October 8th to October 10th 2025. The organizing committee of the workshop will be composed by the current main developers of the code: Daniele Gaggero (researcher at INFN Pisa)\, Silvio Sergio Cerri (researcher at Lagrange Laboratory – Observatoire Côte d’Azur\, in Nice) and Pedro De la Torre Luque (Juan de la Cierva postdoc at UAM and IFT)\, along with Miguel Ángel Sánchez-Conde (associate professor at UAM and IFT). Event related to the I+D+i project CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033\, and topic framed within the research line Origin and composition of the universe: Astroparticles and Cosmology (Astro/Cosmo). \nThe school will have a duration of three days\, in which the first two days will be dedicated to lectures (during the morning)\, covering cosmic-ray related physics  (astrophysical plasmas\, particle interactions\, computational techniques\, etc) and discussing the status of current observations of Galactic diffuse emissions (radio\, X-ray\, neutrino and gamma-ray diffuse backgrounds) and hands-on sessions (during he afternoon)\, while the third day will be dedicated to a number of invited talks about the use of diffuse emissions for indirect dark matter searches and the DRAGON2 code beyond the study of cosmic-ray propagation. \nSEMINARS: \nMiércoles 08/10/25 a las 15:30h \nSpeaker: Manuel Rocamora \nTitle: “Propagation of cosmic rays and production non-thermal radiations with DRAGON and Hermes” \nAbstract: Cosmic-ray measurements have reached unprecented precision in the last decade. These observations are  challenging our standard intepretation of how cosmic rays generated and how they propagate in the Galaxy. Therefore\, it is crucial to achieve accurate predictions to understand the origin of discrepancies with data. On top of this\, these predictions allow us to infer the non-thermal radiations that cosmic rays produce when they interact with Galactic magnetic fields\, radiation fields and gas. This session is dedicated to provide a detailed overview of the DRAGON and Hermes codes and how they can be used to obtain predictions of the cosmic ray\, gamma-ray\, neutrino and even radio diffuse Galactic fluxes that are correlated. \nJueves 09/10/25 a las 12:45h \nSpeaker: José Alberto Rubiño \nTitulo: Diffuse radio emission \nAbstract: Synchrotron emission from cosmic-ray electrons is a powerful tool for probing both the Galactic magnetic field and the energy spectrum of electrons within our Galaxy. This lecture will cover the fundamental principles of synchrotron radiation\, methods for measuring this emission\, and the current state of observations\, with a focus on measurements in the GHz frequency range.

SUMMARY:César Gómez (1954–2025): A rich life in theory
DESCRIPTION:Venue&Time: Blue Room / 10:20 – 17:30 \nMore info: workshops.ift.uam-csic.es/CesarGathering/ \nCésar Gómez\, whose profound contributions to gauge theory\, string theory and quantum gravity were matched by his vision and generosity\, passed away on 7 April 2025. After earning his PhD in Salamanca\, he held positions at Harvard\, the IAS and CERN before joining the CSIC in Madrid\, where he became a founding member of the Instituto de Física Teórica\, his true scientific home. \nHis career spanned key areas of theoretical physics: from the quantum vacuum in QCD and two-dimensional conformal field theory to holography\, black holes and the quantum structure of spacetime. In recent years he embarked on bold new ideas about symmetry breaking and the quantum origin of the universe\, entering one of his most creative periods when his life was cut short. \nBeyond his scientific achievements\, César was a gifted teacher\, an inspiring presence at seminars and a remarkable conversationalist. He leaves behind not only a lasting scientific legacy\, but also the memory of a colleague and friend who enriched every exchange with curiosity\, insight and humanity. \nThe meeting will be an opportunity to celebrate Cesar’s life and career through the personal recollections of some of his friends and collaborators. \nRead CERN’s obituary

SUMMARY:Fast inference for slow likelihoods with probabilistic machine-learning
DESCRIPTION:Speaker: Jesús Torrado from IEM-CSIC\n\n\n\n\nVenue&Time: Red Room / 3:00 PM\n\n\n\nAbstract: Inference for slow likelihoods can require weeks or months\, if possible at all\, with traditional Monte Carlo samplers. This would be the case\, for example\, when fitting expensive non-linear matter spectrum models\, or when characterizing individual long-duration GW events. I will introduce a fast machine-learning Bayesian inference algorithm for general non-Gaussian posteriors with a moderate number of parameters. I will present a pedagogical discussion of some general aspects of it\, such as dealing with the curse of dimensionality\, characterizing a region of interest\, or parallelising active learning. I will show that the total number of expensive likelihood evaluations can be reduced by at least two orders of magnitude compared to traditional Monte Carlo methods\, at low overhead costs and no pre-training. I will demonstrate its performance on a couple of real cosmological and GW problems.

SUMMARY:SPS Journal Club: 'Landau-Ginzburg Models and Flux Vacua'
DESCRIPTION:Speaker: Muthusamy Rajaguru (IFT Madrid)\n\n\n\n\nVenue&Time: Red Room / 12:00 PM\n\n\n\nAbstract: In this talk\, I will give an overview of recent progress that has been made in constructing non-geometric flux vacua. In particular\, I will focus on type IIB string compactifications where the internal geometry is described by the 2^6 and 1^9 Landau-Ginzburg (LG) models. These LG models have no Kähler moduli and allow us to realize GKP-type vacua explicitly in the interior of the complex structure moduli space.  I will summarize the properties of these vacua and their implications for certain Swampland conjectures.\n\nRelevant literature – 2503.16599\, 2407.16756\, 2407.16758\, 2406.03435\, 2306.15714\, 2203.15818

SUMMARY:Delta N formalism: non-linear evolution of scalar and tensor perturbations during inflation
DESCRIPTION:Speaker: Danilo Artigas\n\n\nInstitution: Kyoto University\n\n\nLocation&Place: IFT Seminar Room/Red Room\n\n\n\n\n\nAbstract:\n\n\nLinear-perturbation theory has proven to be an extremely powerful tool to compare inflationary models with observational data. Recently\, the newcoming high-precision observations call for predictions beyond linear perturbations. Such effects are known to be relevant for example in the production of primordial black holes or scalar-induced gravitational waves. The delta N formalism proposes to capture some of these non-linearities by describing the universe as a set of homogeneous patches evolving independently. After reviewing its formulation\, I will apply it to the case of a single scalar field following a slow-roll evolution\, briefly interrupted by a phase of ultra-slow roll where the potential is nearly flat. Taking care of the correlation of the patches\, I will show how to obtain correlation functions of scalar perturbations. As a final note\, I will briefly show how this procedure can also be applied to describe primordial gravitational waves.

SUMMARY:To bind or not to bind\, a tale of two nucleons
DESCRIPTION:Speaker: André Walker-Loud (LBNL) \nVenue&Time: Red Room / 11:30 AM \nAbstract: Our ability to understand the emergence of nuclear physics from the Standard Model requires an understanding two nucleon interactions from the underlying quark and gluon degrees of freedom. Due to the non-perturbative nature of QCD at low-energies\, the only method to provide such predictions\, with quantifiable uncertainties is lattice QCD. Yet the application of lattice QCD to the two-nucleon problem is beset by a number of significant challenges\, such that it has remained uncertain whether di-nucleon systems form bound states at pion masses heavier than nature. I will present recent work exploring this question with all varieties of methods in the literature\, including the HAL QCD potential method\, on a single set of gauge ensembles\, enabling for a direct comparison of the methods.

SUMMARY:PhD dissertation: Quantum Information & its interplay with High-energy Physics
DESCRIPTION:Alexander Bernal (IFT) PhD dissertation. \nSupervisor: Alberto Casas & Jesús Moreno \nVenue&Time: ¨Blue Room / 10:00 AM \nAbstract: \nThis thesis explores the intersection of Quantum Information Theory (QIT) and High-Energy Physics. We demonstrate the presence of entanglement and Bell nonlocality in vector boson systems resulting from scalar and pseudoscalar particle decays\, focusing on the H→ZZ process and generalizing to broader Lorentz-invariant scenarios. We also develop a method for quantum state tomography through angular distributions in scattering processes. Beyond high-energy applications\, the thesis contributes to the field of QIT by providing new tools for studying genuine multipartite entanglement\, exploring CHSH nonlocality violation in hybrid systems\, and introducing operational definitions for fundamental concepts like quantum dimensionality and classicality. These latter results connect with core ideas in QIT such as the accessible information\, the joint measurability\, and the quantum steering.

SUMMARY:Stirring up the intracluster medium with substructures
DESCRIPTION:Speaker: Go Ogiya from Zhejiang University\n\n\n\nVenue&Time: Red Room / 3:00 PM\n\n\n\n\nAbstract: \nThe origin of the turbulent motion of the intracluster medium (ICM) has been a longstanding open question. Stirring by substructures (member galaxies and dark matter subhaloes) orbiting within a galaxy cluster is a possible mechanism to generate and maintain the ICM turbulence. We develop a semi-analytic model considering three processes of energy transfer from substructures to the ICM (dynamical friction\, ram pressure\, and sloshing)\, and propagation and dissipation of the deposited energy. The model reproduces the gas velocity structure derived from hydrodynamical simulations. We find that dynamical friction is responsible for explaining the strong turbulence (~ 500 km/s) in the cluster outskirts (> 1 Mpc)\, while sloshing explains the mild turbulence (~100 km/s) in the cluster centre. In the talk\, we will also discuss implications for X-ray observations of the new generation\, such as XRISM and eROSITA.

SUMMARY:SPS JC: de Sitter and Machine Learning
DESCRIPTION:SPS Journal Club\n\nSpeaker: Bruno De Luca\n\nVenue&Time: Red Room / 12:00\n\nAbstract: \nThe problem of constructing de Sitter vacua in quantum theories of gravity is constrained by no-go theorems and made computationally challenging by the absence of supersymmetry. A popular approach to make it more tractableis to start from a supersymmetric compactification\, such as on a Calabi-Yau manifold. This simplification comes at the price of greatly restricting the allowed physical sources and possible geometries.\n\nIn this introduction\, I will discuss some of my works on how to break supersymmetry at the compactification scale by directly solving the equations of motion. This allows for more general internal geometries and thus more general physical configurations\, including four-dimensional de Sitter vacua supported by Casimir energy on negatively-curved manifolds\, and scale-separated AdS4 vacua.\n\nHowever\, describing the corresponding geometries in detail can sometimes require to solve Einstein-like PDEs on non-trivial manifolds. This problem is intractable even numerically\, with standard methods. Luckily\, Machine Learning is emerging as a method to overcome these difficulties\, and we will discuss a recent proposal for using Machine Learning techniques to explicitly construct negatively-curved geometries.\n\nTime permitting\, we will also describe the other way around: how we can use insights from physics to design algorithms with broad applicability to Machine Learning and beyond\, focusing on optimization and sampling algorithms obtained from energy-preserving chaotic Hamiltonians with non-standard kinetic terms.\n\n\n\nSome references:\n2501.00093\n2104.13380\n2212.02511\n2201.11137

SUMMARY:Kaluza-Klein Amplitudes in AdS: the Virasoro-Shapiro and the Veneziano Amplitudes
DESCRIPTION:Speaker: Bo Wang from Zhejiang U. Inst. Mod. Phys. \nVenue&Time: Red Room / 3:00 PM \nAbstract: \nI will report recent progress on AdS Virasoro-Shapiro and Veneziano amplitudes for half-BPS operators with arbitrary Kaluza-Klein modes. The key ingredient is a bootstrap built directly in the world-sheet representation\, together with a novel formalism. This approach yields a structural string description of AdS amplitude and a precise correspondence with correlators in N=4 SYM: at first curvature order we obtain a unique solution. I will also discuss the applications to broader holographic models beyond AdS5*S5.

SUMMARY:PhD dissertation: Advancing Gravitational Wave Data Analysis and  Exploring New Sources
DESCRIPTION:Gonzalo Morrás PhD dissertation.\n\nSupervisor: Juan García-Bellido\n\nVenue&Time: Blue Room / 10:30 AM\n\n\nAbstract: Gravitational wave (GW) astronomy has opened a new window onto the Universe\, allowing us to study compact objects and fundamental physics. This thesis develops new methods and models to improve the detection and interpretation of GW signals\, with a focus on exotic and underexplored sources. It includes pioneering searches for close hyperbolic encounters\, studies of low-mass and sub-solar-mass binaries\, analyses of local cosmic effects on merger rates\, and the development of advanced waveform models and data analysis algorithms. These contributions enhance our ability to uncover new astrophysical phenomena and will support future GW observations with current and next-generation detectors.

SUMMARY:God plays dice with the world.  The story of quantum mechanics
DESCRIPTION:What is matter? A question that has fascinated—and at times tormented—some of the brightest minds of the twentieth century. Max Planck\, Albert Einstein\, Niels Bohr\, Erwin Schrödinger\, Werner Heisenberg\, Max Born\, Wolfgang Pauli\, and Paul Dirac all grappled with it\, debating fiercely\, colliding over equations and experiments\, in their attempt to decipher the very essence of physical reality. Out of this intellectual struggle was born quantum mechanics\, a theory that unveils a microscopic universe ruled by probability—an outcome that Einstein found so unsettling that he refused to accept its philosophical implications. \nA century after its first complete formulation\, in the seminar we retrace the history of this scientific revolution through its protagonists and its places: from the hushed courtyards of Cambridge colleges to the windswept cliffs of Helgoland\, amid biographies worthy of an adventure novel and exchanges of fiery letters. The result is a captivating narrative that pays tribute to an unrepeatable season in the history of science.

SUMMARY:Vacuum stability for gravity compactifications
DESCRIPTION:Speaker: Alessandro Tomasiello (Milano Bicocca)\n\n\nVenue&Time: 15:00 / Red Room\n\n\nAbstract: Compactifying from higher dimensions typically produces many different vacuum solutions; this leads to multiple possible decay channels\, mediated by the nucleation of bubbles. In string theory\, the latter can be expanding D-branes. Supersymmetry provides a stabilization mechanism; I will describe how to replicate it for supersymmetry-breaking vacua\, with some partial success.

SUMMARY:Measuring Stochastic Gravitational Wave Backgrounds with Pulsar Timing Arrays
DESCRIPTION:Speaker: Mauro Pieroni\n\n\nInstitution: IEM-CSIC\n\n\nLocation&Place: Red Room\n\n\nAbstract:\n\n\nMy talk focuses on using Pulsar Timing Array (PTA) data to measure Gravitational Waves (GWs). In particular\, I will focus on Stochastic GW Background (SGWB) measurements. After a general introduction to the topic\, I will discuss a new (simplified) approach to constrain SGWBs with PTA data. This methodology significantly reduces the computational cost of the analysis\, opening up new avenues to explore the constraining power of PTA experiments. Within this framework\, I’ll revisit the constraints current and future PTA experiments can set on cosmological scenarios.

SUMMARY:Aspects of inflation beyond the single-field\, slow-roll regime
DESCRIPTION:Speaker: Alejandro Pérez Rodríguez\n\n\nLocation&Place: Red Room\n\n\nAbstract:\n\n\nIn this thesis\, we explore two departures from the single field\, slow-roll paradigm of inflation. The first part is dedicated to warm inflation. We revisit the theory of linear perturbations in this framework\, develop computational techniques for the calculation of the primordial power spectrum and apply them to the analysis of CMB constraints and the production of primordial black holes. The second part focuses on the primordial non-Gaussianity arising from a phase of ultra slow-roll during single field inflation. We study the scope and limitations of the classical delta N formalism as a probe of such non-Gaussianity and determine the extent of its correspondence with the stochastic delta N formalism. \nSupervisor: Guillermo Ballesteros Martínez
