SUMMARY:Pheno Journal Club: Coherently enhanced decoherence and cloud substructure of atom interferometers
DESCRIPTION:Speaker: Pablo Blanco Mas (IFT)\n\n\n\n\n\n\n\n\nVenue & Time: Grey Room 3 / 15:00\n\nAbstract: We study how coherent scattering of a background gas off an atom (or other matter) interferometer can lead to enhanced signals from phase shifts and contrast loss. We focus on the inclusion of realistic features of atom interferometers such as finite temperature\, cloud substructure\, and time-dependent cloud radii. The inclusion of these effects\, extending beyond the previously considered point-like cloud approximation\, naturally allow us to study the smooth transition between the coherent and incoherent scattering regimes. We discuss how the formalism presented herein can be tested in the laboratory (with near-infrared photons or an eV-scale electron gun)\, and discuss an application for the detection of dark matter interacting via long-range forces.

SUMMARY:Bubble wall dynamics from nonequilibrium quantum field theory
DESCRIPTION:Speaker: Matthias Carosi from Munich\, Tech. U.\n\n\n\n\n\n\n\n\nVenue & Time: Red Room / 15:00\n\nAbstract:\n\n\n\nFirst-order phase transitions in the early universe are a unique probe of physics beyond the Standard Model\, with potential implications for electroweak baryogenesis\, the formation of primordial black holes\, magnetogenesis and the production of dark matter. Upcoming gravitational wave detectors may capture the imprint of such transitions\, but to extract theoretical insights from these signals requires a precise understanding of the underlyingdynamics.\nIn this talk\, I show how the language of nonequilibrium quantum field theory\, combined with the two-particle-irreducible effective action\, provides anatural framework for describing the dynamics of a bubble after nucleation. After a brief introduction to the closed-time-path formalism\, I derive the dynamical equations governing the bubble and the plasma\, and identify all sources of friction for thebubble expansion. This framework unifies the pre-existing approaches within a single\, consistent description. In the ultrarelativistic regime\, I demonstrate how to compute the friction induced by the pair production of heavy scalar particles and outline the contributions of particle mixing andtransition radiation.

SUMMARY:Recent results on the origin of Galactic CRs from gamma-ray astronomy
DESCRIPTION:Speaker: Guillem Martí-Davesa (INFN-Trieste)\n\n\nVenue&Time: Red Room / 15:00\n\nAbstract: Supernovae have traditionally been invoked as the dominant cosmic ray factories within our Galaxy\, capable of accelerating protons up to PeV energies. In this seminar we will discuss to what extent such a view holds today\, and if alternative source populations could instead be relevant actors. Thus\, a comprehensive review of recent findings on supernovae\, stellar clusters\, and microquasars will be presented\, with particular emphasis on observational signatures above GeV energies.

SUMMARY:Seminar: 'Entanglement asymmetry and spontaneously broken symmetries'
DESCRIPTION:Speaker: Eduardo García-Valdecasas (SISSA\, Trieste) \nVenue&Time: Red Room / 15:00 \nAbstract: Entanglement asymmetry is a relative entropy that faithfully measures the breaking of a symmetry in a subregion. We explore some applications in theories with spontaneously broken higher form symmetries. We will start with discrete abelian symmetries and then discuss continuous symmetries. We will be able to recover the Mermin-Wagner-Coleman theorem and refine it for the case of subregions.

SUMMARY:Quantum Information Journal Club: Randomized truncation
DESCRIPTION:Speaker: Aram Harrow (MIT) \nVenue&Time: Grey Room 3 / 11:30 \nAbstract: Given a vector v\, what is the closest k-sparse vector? The answer to this question is usually that we should take the largest k entries of v. It turns out that we can do better with randomized approximations. When approximating pure bipartite entangled states with states of low Schmidt rank\, this means that mixed approximations outperform pure approximations. This fact has application to classical algorithms for matrix product states by improving the truncation step\, and to quantum algorithms for Hamiltonian simulation.\nJoint work with Angus Lowe and Freek Witteveen. \nhttps://arxiv.org/abs/2510.08518

SUMMARY:SPS Journal Club: Weak Gravity and Perturbative Black Holes
DESCRIPTION:Speaker: Matteo Lotito (IFT) \nVenue&Time: Red Room / 12:00 \nAbstract: \nI present a brief summary of the derivation of the Weak Gravity Conjecture within perturbative string theory\, following [2403.14449]\, and highlight possible gaps that may hinder a fully consistent proof. I then analyze the existence and properties of the black hole solutions whose extremality bounds are compared to the string spectrum in the statement of the WGC. This analysis demonstrates that the black hole solutions we employ in our setup are reliable and do not undermine the validity of our results. \n

SUMMARY:Old Journal Club: Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation
DESCRIPTION:Pablo Blanco (IFT) will present Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation de Rabindra N. Mohapatra\, Goran Senjanovic\, Jul\, 1980 Phys.Rev.D 23 (1981) 165. \nAbstract: \nUnified electroweak gauge theories based on the gauge group SU(2)L×SU(2)R×U(1)B−L\, in which the breakdown of parity invariance is spontaneous\, lead most naturally to a massive neutrino. Assuming the neutrino to be a Majorana particle\, we show that smallness of its mass can be understood as a result of the observed maximality of parity violation in low-energy weak interactions. This result is shown to be independent of the number of generations and unaffected by renormalization effects. Phenomenological consequences of this model at low energies are studied. Observation of neutrinoless double-β decay will provide a crucial test of this class of models. Implications for rare decays such as μ→eγ\, μ→eee¯\, etc. are also noted. It is pointed out that in the realm of neutral-current phenomena\, departure from the predictions of the standard model for polarized-electron-hadron scattering\, forward-backward asymmetry in e+e−→μ+μ−\, and neutrino interactions has a universal character and may be therefore used as a test of the model.

SUMMARY:Top Ten Foundational Ideas of Theoretical Physics
DESCRIPTION:Speaker: Anthony Zee from Kavli Institute for Theoretical Physics and the Departmentof Physics\, University of California\, Santa Barbara\, CA\, USA \n\nVenue&Time: Red Room / 3:00 PM \n\nAbstract: \n\nI will list and discuss the ten foundational ideas of theoretical physics. The lecture is based on a popular book with the same title published by Princeton University Press on June 17\, 2025. The book is meant to provide a sweeping overview of theoretical physics rather than a morass of details\, and thus this talk may be suitable\, not only for students of physics\, but also for those who are interested in theoretical physics but do not know much about it.

SUMMARY:10th IBS/IFT workshop: Dark World to the Swampland
DESCRIPTION:The IBS-IFT Workshop is a regular event organized jointly by IFT and IBS-CTPU\, this year reaching its tenth anniversary. \nThe aim of the workshop is share ideas\, foster collaborations\, and to discuss recent developments in theoretical physics. \nThe event is organized over two weeks. The first week\, November 4-7\, will focus on String Phenomenology  \nThe Center for Theoretical Physics of the Universe is one of the 30 centers of the Institute of Basic Science in South Korea. The IBS-CTPU carries out research on particle physics and cosmology\, which aims to understand nature at the most fundamental level and answer the big questions about the origin of the universe. \nThe Institute for Theoretical Physics IFT UAM-CSIC is a joint research center belonging to the Spanish National Research Council (CSIC) and the Universidad Autónoma de Madrid (UAM). It is the only Spanish center dedicated entirely to research in Theoretical Physics. The IFT members develop research in the frontiers of Elementary Particle Physics\, Astroparticles\, and Cosmology\, in order to understand the fundamental keys of Nature and the Universe. \nWith this workshop we want to try to advance our understanding of quantum gravity\, mainly through the swampland program\, by refining several of the conjectures that have been put forth in the program to bridge the gap between effective field theories and the UV completion as quantum gravity.

SUMMARY:HoloClub: 'N=1 Supergravity from Super Virasoro TQFT'
DESCRIPTION:Speaker: Sounak Pal (Indian Institute of Technology) \nVenue&Time: Grey Room 3 / 11:30 \nAbstract: I will discuss some aspects of 2D and 3D quantum gravity in\nthe language of Topological quantum field theory (TQFT). Recent\ndevelopments include calculating various gravity partition functions\nin AdS3 using descriptions of Liouville conformal field theory (CFT).\nWe extend this formalism for the N=1 super Liouville case and use\nsuper-Teichmüller TQFT to compute various partition functions of\ndifferent on-shell manifolds (admitting a hyperbolic metric with\nconstant negative Ricci scalar). I will also touch upon some aspects\nof quantum chaos and ensemble holography. I will also discuss some\npossible future extensions at the end.

SUMMARY:Towards spectral bounds in 6d N=(1\,0) supergravity
DESCRIPTION:Speaker: Seung-Joo \n  \nVenue & Time: Tuesday\, Nov. 4th / 17:00 \n  \nAbstract: In this talk we will discuss spectral bounds in 6-dimensional N=(1\,0) supergravity. Specifically\, considering F-theory vacua on generic base surfaces\, we will constrain the U(1) vector and the tensor sectors in turn\, to present explicit spectral bounds on the respective sectors. Speculations will also be made as to how the F-/string-theoretic bounds may possibly generalize to the EFT counterparts. This seminar is related to the I+D+i project whose reference is CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033. The topic is framed within the following research line: Strings and quantum gravity (Gravity/Strings).

SUMMARY:Machine Learning for Time-Domain Astrophysics
DESCRIPTION:Speaker: Alex Gagliano (IAIFI/MIT) \nVenue&Time: Blue Room / 3:00 PM \nAbstract: The time-evolving night sky is rich with variable stars\, supernovae\, and merging neutron stars. Wide-field imaging surveys that monitor this variability produce gappy\, multi-modal observations that demand scalable\, uncertainty-aware models for physical inference. In this talk\, I’ll survey my recent work in building machine learning methods for time-domain astrophysics\, with a focus on learning representations of our data for classification\, physical inference and the discovery of astrophysical anomalies. I’ll introduce Minuet\, a compact host-galaxy image encoder trained with diffusion modeling; and a mixture-of-experts model that fuses supernova light curves and spectra while preserving modality-specific information and yielding calibrated posteriors. I’ll conclude by outlining three areas at this intersection with the greatest potential to drive discovery in the coming years: better physical models\, scalable population studies\, and ML-guided survey optimization. \nThis seminar is related to the I+D+i project whose reference is CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033. The topic is framed within the following research line: Origin and composition of the universe: Astroparticles and Cosmology (Astro/Cosmo).

SUMMARY:Machine Learning Journal Club: 'Hierarchical Simulation-Based Inference of Supernova Physics'
DESCRIPTION:Speaker: Alex Gagliano (IAIFI/MIT) \nVenue&Time: 11:00 / Grey Room 2 \nAbsrtact: Supernovae are powered by diverse physical mechanisms such as radioactive decay\, circumstellar interaction\, and magnetar spin-down\, but distinguishing among them from light curves alone remains a major challenge. In this talk\, I’ll present a hierarchical simulation-based inference framework that jointly infers both the dominant power source and the key physical parameters of supernovae. By training conditional neural density estimators end-to-end across multiple physical models\, this approach yields calibrated posteriors even in regions of strong degeneracy. I’ll highlight the model’s performance on synthetic data and outline plans to fine-tune the model for population-level studies of diverse explosion physics.

SUMMARY:SPS Journal Club: Holographic constraints on AdS flux vacua
DESCRIPTION:Speaker: Antonia Paraskevopoulou (Munich\, Max Planck Inst. and LMU Munich) \nVenue & Time: Red Room / 12:00 \nAbstract: In this talk\, I will argue that the covariant entropy bound poses non-trivial restrictions on anti-de Sitter(AdS) flux vacua. After motivating the bound on AdS\, we will see how it naturally arises in the context of the supergravity equations of motion\, based on some reasonable assumptions. In four dimensions\, we argue that the bound suggests a lower bound on the superpotential\, as we will verify in examples. Based on work in progress with N. Cribiori and T. Van Riet.

SUMMARY:Seminar: 'BipoSH: Structured test bed for cosmic isotropy violation'
DESCRIPTION:Speaker: Tarun Souradeep (Raman Research Institute\, Bengaluru\, India) \nVenue & Time: Red Room / 3:00 PM \nAbstract: The Cosmological Principle\, a fundamental tenet of the ‘standard model of cosmology’\, predicates a statistically isotropic distribution of fluctuations in the measured cosmic microwave background (CMB) temperature and polarization sky maps. Enigmatic anomalies claimed in the WMAP and Planck CMB sky maps\, and some other recent observations\, could challenge the standard model. However\, these claims need to be cast in an objective mathematical framework and established with statistical rigor. Bayesian inference of the underlying covariance structure of random fields on the sphere in the Bipolar Spherical Harmonic (BipoSH) representation\, developed in our research program\, provides such a framework. We review some recent inferences drawn from Planck data and discuss the future prospects with proposed CMB observations.

SUMMARY:Seminar: Average-case quantum complexity from glassiness
DESCRIPTION:Speaker: Alexander Zlokapa (MIT) \nVenue & Time: Red Room / 11:30 \nAbstract: In the classical setting\, glassiness characterizes many natural problems (e.g.\, random k-SAT) and underlies average-case hardness by obstructing a family of “stable” classical algorithms (e.g.\, constant-time Langevin dynamics). In this work\, we develop analogous quantum results. Our techniques\, based on quantum optimal transport\, differ significantly from classical probabilistic approaches due to the sign problem in the absence of a known eigenbasis. We show that quantum glassiness obstructs stable quantum algorithms\, including constant-time Lindbladian dynamics (even when starting from the maximally mixed state). Using the replica trick\, we also find that random 3-local Pauli Hamiltonians are quantumly hard and give evidence that random k-local Hamiltonians are quantumly easy for sufficiently large constant k. This differs from the analogous classical (Ising\, glassy phase for all k) and fermionic (SYK\, never glassy for any k) k-local ensembles. (Talk based on arXiv:2510.08497.)

SUMMARY:SPS Journal Club: 'Flux Backtracking and Decoupling of Scale Separated AdS Vacua'
DESCRIPTION:Speaker: Fien Apers (IFT) \nVenue & Time: Red Room / 12:00 \nAbstract: I will explain how the flux backtracking method (https://arxiv.org/pdf/2506.03314) can be used to reconstruct the D-brane configuration whose near-horizon region realises the DGKT vacua. As an application\, I will show how this reconstructed geometry allows one to verify whether the corresponding D-brane theory decouples from bulk gravity.

SUMMARY:Seminar: 'Classical constant electric fields and the Schwinger effect in de Sitter'
DESCRIPTION:Speaker: Roberto Vega-Morales \nVenue&Time: Red Room / 15:00 \nAbstract: In this talk I will discuss constant classical electric fields and the Schwinger effect in de Sitter space\, which has potential implications for magnetogenesis and inflationary dark matter production. I will first go through the conditions for sustaining a constant electric field in de Sitter space before reviewing the calculation of the Schwinger current\, pointing out puzzling results in previous calculations found in the literature and how we have resolved them. I will then comment on current and future directions related to this topic. This talk is based on arXiv:2508.14973. \nSeminar related to the I+D+i project whose reference is CEX2020-001007-S\, funded by MCIN/AEI/10.13039/501100011033.
