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:Ciclo de Charlas IFT + Residencia: 'Física fundamental en clave cuántica'
DESCRIPTION:Con motivo del Año Internacional de la Cuántica\, el Instituto de Física Teórica (IFT\, UAM-CSIC) celebra una nueva edición de su ya tradicional Ciclo de Conferencias de Física Fundamental en la Residencia de Estudiantes. A lo largo de cuatro jornadas\, investigadoras e investigadores del IFT\, junto a figuras internacionales invitadas\, abordarán el papel central que juega la física cuántica en nuestra comprensión del universo. Desde la computación cuántica hasta la teoría de cuerdas\, pasando por los aceleradores de partículas y las conexiones inesperadas entre la física y el arte\, el ciclo ofrecerá al público general una panorámica actualizada de la investigación física más avanzada. \nFechas: 6\, 7\, 13 y 14 de noviembre de 2025 \nPROGRAMA\nJueves\, 6 de noviembre\n18:00 | Álvaro M. Alhambra (IFT UAM-CSIC): “Computación cuántica\, perspectivas de futuro” \nLa computación cuántica se encuentra en un punto de inflexión: tras décadas de desarrollo teórico\, los primeros dispositivos experimentales empiezan a mostrar su potencial. ¿Qué podemos esperar en los próximos años? ¿Qué problemas reales podría resolver un ordenador cuántico? En esta charla exploraremos las bases de esta nueva tecnología\, los retos actuales y las perspectivas científicas y tecnológicas a medio y largo plazo. \n19:30 | Mª Ángeles Pérez García (USAL): “Deconstruyendo una estrella de neutrones” \nDeconstruyendo una estrella de neutrones es un viaje al corazón de uno de los objetos más extremos del universo. A partir de los restos de una supernova\, estas estrellas concentran más masa que el Sol en un radio de apenas una docena de kilómetros. En este viaje buscamos “desarmarlas” conceptualmente: entender cómo la materia se comporta cuando la presión convierte los átomos en un mar de neutrones superfluidos. Combinaremos física cuántica\, y gravedad para entender sus capas y procesos internos. La idea es explorar cómo estos fascinantes objetos pueden ayudarnos a descifrar los misterios del interior estelar y\, en última instancia\, los límites mismos de la materia. \nViernes\, 7 de noviembre\n18:00 | Cumrun Vafa (Harvard): “Puzzles para descifrar el universo” \nDebajo de todas las complejas y formidables estructuras matemáticas que formulan las leyes físicas\, descansan simples pero profundas verdades. Son por estas verdades sencillas\, y no por los detalles técnicos complicados\, por lo que se esfuerzan los científicos cuando tratan de desvelar las leyes de la naturaleza. Afortunadamente\, estas ideas clave pueden ilustrarse a menudo con sencillos puzles matemáticos (rompecabezas\, acertijos\,…). En esta charla expondré varios ejemplos de estos sencillos puzles y mostraré cómo pueden arrojar luz sobre algunos de los conceptos más profundos de la física. Además\, se pedirá a los asistentes que participen en la resolución de los puzzles durante la charla\, que será muy interactiva. Está basada en mi libro “La Simplicidad del Universo” (“Puzzles to Unravel the Universe”\, en la versión original)\, dirigido al público en general y que no requiere tener amplios conocimientos de matemáticas o física\, sólo un mínimo de curiosidad. \nEsta charla se desarrollará en inglés y contará con un equipo de traducción simultánea. \nJueves\, 13 de noviembre\n18:00 | Ángel M. Uranga (IFT UAM-CSIC): “1000 maneras cuánticas de destruir el universo”. \nVivimos en un universo que parece estable… pero ¿y si solo lo fuera por ahora? Las leyes cuánticas permiten escenarios tan exóticos como inquietantes: desde la desintegración del vacío debido a inestabilidades en el campo de Higgs\, hasta procesos más profundos que podrían surgir de una teoría aún incompleta de la gravedad cuántica. En esta charla exploraremos algunos de estos mecanismos hipotéticos —pero físicamente plausibles— que podrían\, en última instancia\, provocar el colapso del universo tal y como lo conocemos. \n19:30 | Ana Cueto (UAM): “El futuro de la cuántica en los grandes aceleradores” \n¿Qué papel jugará la física cuántica en la próxima generación de aceleradores de partículas? Con instalaciones como el LHC y sus sucesores\, las tecnologías que estudian la estructura de la materia entran en una nueva era. Esta charla analizará qué descubrimientos podríamos tener en el horizonte. \nViernes\, 14 de noviembre\n19:00 | Esperanza López (IFT UAM-CSIC): “Música y experiencias cuánticas” \nLa física cuántica ha transformado nuestra visión del mundo\, y su belleza abstracta ha inspirado otras disciplinas\, como la música. En esta charla singular\, exploraremos los vínculos y paralelismos entre la experiencia estética y el asombro científico. \nCon la colaboración de los siguientes artistas: \nMiguel Álvarez-Fernández: Artista sonoro\, compositor\, musicólogo y ensayista de reconocido prestigio. Desde 2008 dirige y presenta el programa Ars Sonora en Radio Clásica. \nAlvaro Pérez: Saxofonista y compositor. Reconocida figura del Jazz y la improvisación\, con una extensa discografía. Ha tocado con varias orquestas\, incluyendo la de RTVE como solista. \nRoberto Jabonero: Violinista y productor musical. Ha formado parte de importantes agrupaciones de clásica y moderno del panorama español. Es director de la Escuela de Música de Tres Cantos. \nBruno Dozza: Autor de obras de cámara\, sinfónicas y escénicas estrenadas en festivales y salas en Europa\, Asia y Estados Unidos. Ha colaborado con destacados artistas internacionales. \nCarlos de la Blanca: reconocido y joven pianista. Ha dado numerosos recitales en tanto en España como en el extranjero. Ha sido premiado en varios concursos nacionales e internacionales en España.

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: 'Gravitational Lensing of Waves: a new window into cosmology and fundamental physics'
DESCRIPTION:Speaker: Miguel Zumalacárregui from Max Planck Institute for Gravitational Physics (Albert Einstein Institute). \nVenue&Time: Red Room / 3:00 PM \nAbstract: Gravitational lensing\, the bending of light by gravity\, is essential for interpreting astronomical observations and provides key insight into astrophysics\, cosmology\, and fundamental physics. A new frontier in gravitational lensing intersects with another key prediction of Einstein’s theory: gravitational waves\, fluctuations of space-time produced by the collision of black holes and neutron stars. Like light\, gravitational waves are deflected and magnified by the intervening matter distribution\, but their unique properties (low frequency\, lack of absorption and ab-initio emission models) enable novel signatures and applications. I will present the phenomenology of lensed gravitational waves and the science they will deliver to identify high-redshift sources and probe dark-matter and new gravitational fields. As guiding example I will focus on GW231123: the first compelling lensed black hole merger candidate\, its interpretation and consequences.

SUMMARY:Pheno Journal Club: 'Is the Strong CP Problem Really a Problem?'
DESCRIPTION:Speaker: Giulio Barni (IFT) \nVenue & Time: 14:30 – 15:30 \nAbstract: The vanishingly small value of the QCD θ-angle inferred from neutron EDM bounds is usually taken as evidence for the Strong CP Problem\, prompting a wide range of proposed solutions. In this talk\, I will first review what the Strong CP Problem is: why a generic θ term in QCD leads to large CP violation\, and how current experiments force θ ≲ 10e-10. I will then summarize the main solution strategies\, including the Peccei–Quinn axion\, parity- or CP-based models\, and other less conventional ideas. The second part of the talk will focus on a more conceptual question raised in recent years: does the Strong CP Problem actually exist\, or could θ be unphysical once confinement and the full structure of QCD are properly taken into account? Building on the recent analysis of Benabou\, Hook\, Manzari\, Murayama and Safdi (arXiv:2510.18951)\, I will discuss this debate\, highlighting what lattice QCD teaches us about θ-dependence\, topological sectors\, and the neutron EDM.

SUMMARY:String\, Pheno and the Swampland Journal Club: 'Anomaly-induced vanishing of brane partition functions'
DESCRIPTION:Speaker: Michelangelo Tartaglia (IFT) \nVenue & Time: Red Room / 12:00 \nAbstract: In the presence of ‘t Hooft anomalies\, backgrounds for the symmetries of a quantum field theory can lead to non-conservation of Noether currents\, or more generally\, to the presence of charged insertions in the path integral. When there is a net background charge\, the partition function evaluated on closed manifolds will vanish. For anomalous symmetries\, this statement can also be understood as the anomaly theory giving rise to a non-trivial anomalous phase for the partition function even for “rigid” transformations which leave all background fields unchanged. We use the generalisation of this second viewpoint to the setting of anomalous higher-form symmetries in order to show vanishing of the partition function for a number of examples\, both with and without a Lagrangian description. In particular\, we show how to derive from these considerations the analogue of the Freed-Witten anomaly cancellation condition for the M5-brane\, and also that for the D3-brane in S-fold backgrounds.

SUMMARY:Seminar: Constraining Muon decay parameters from CEvNS measurements at Spallation Sources
DESCRIPTION:Speaker: Suraj Prakash\, IFIC (Valencia)\n \nVenue&Time: Red Room / 3:00 PM \nAbstract: The talk will present a study of the sensitivity of COHERENT-like experiments to non-standard neutrino interactions within the vWEFT framework\, i.e. low-energy EFT with additional right-handed Dirac neutrinos. Our analysis incorporates\, for the first time\, flavor-general New Physics effects in both neutrino production (from pion and muon decays) and neutrino detection\, through Coherent Elastic Neutrino-Nucleus Scattering (CEvNS). As a special case\, we will highlight how CEvNS data provide an alternative probe for muon decay parameters\, for neutrino experiments where muon decay is a source of neutrinos. We will further illustrate how the results can be conveniently formulated in compact form and the ease with which they can be implemented in existing or future analyses using effective nuclear charges. Finally\, We will discuss numerical results based on current COHERENT data\, and also present estimates for the sensitivity of future measurements.

SUMMARY:PhD dissertation: 'Shedding light on extended scalar sectors'
DESCRIPTION:By Víctor Enguita \nVenue & Time: Red Room / 12:00 \nAbstract: \nThe Standard Model has a number of traits which are surprising from the theoretical perspective and may hint the presence of some underlying hidden structure beyond the SM. In this thesis\, we explored some of the open problems which materialize from those traits and could be solved by the presence of an extended scalar sector. First\, we considered axion-like particles (ALPs) using an Effective Field Theory (EFT) approach and imposed improved limits on their CP-odd couplings to fermions. The remainder of the thesis was devoted to the Electroweak hierarchy problem (EWHP). We presented two original works which follow two different guiding principles\, one traditional and the other rather innovative: symmetry and near-critical dynamics. The first among these works presents non-abelian discrete symmetries as able to suppress large radiative corrections and stabilize the masses of scalar particles. In the second contribution\, we argue that the small observed mass of the Higgs could be a trademark of the near-criticality of the Higgs sector\, backed by the observation that every parameter in the Higgs potential seems in fact to also be near-critical.  We explore the consequences of this fact using the so-called “Higgs metastability bound” in the case of a concrete model—the low-scale Majoron model—and demonstrate that this justification of the mass of the Higgs implies new experimental signals in future experiments and in particular\, in the future colliders. We argue that this conclusion is actually more general and should apply to wider contexts than the concrete model analysed.\nSupervisors: Belén Gavela & José Miguel No
