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: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: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.

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:EDI Trainings: 'Intersectionality. Reflection on identity\, privilege and positioning in academia'
DESCRIPTION:Speaker: Shannah Khan. Director of Intersect Madrid \nVenue & Time: Blue Room / 3:30 PM \nAbstract: This workshop offers a space for reflection and dialogue to explore how our personal identities\, experiences\, and social positions influence the way we participate in academic contexts. Through participatory activities\, it seeks to foster a deeper understanding of intersectionality and the role that privilege and position play in our interactions and perspectives within academia.

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.
