Speaker: Guillem Martí-Davesa (INFN-Trieste) Venue&Time: Red Room / 15:00 Abstract: 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 […] |

Speaker: Eduardo García-Valdecasas (SISSA, Trieste) Venue&Time: Red Room / 15:00 Abstract: 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 […] |

Speaker: Aram Harrow (MIT) Venue&Time: Grey Room 3 / 11:30 Abstract: 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 […] |

Speaker: Matteo Lotito (IFT) Venue&Time: Red Room / 12:00 Abstract: I present a brief summary of the derivation of the Weak Gravity Conjecture within perturbative string theory, following , 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 […]

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. Abstract: Unified 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.

Speaker: Seung-Joo Venue & Time: Tuesday, Nov. 4th / 17:00 Abstract: 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 […] |

Speaker: Alex Gagliano (IAIFI/MIT) Venue&Time: Blue Room / 3:00 PM Abstract: 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 […] |

Speaker: Alex Gagliano (IAIFI/MIT) Venue&Time: 11:00 / Grey Room 2 Absrtact: 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 […]

Speaker: Cumrun Vafa (Harvard) Venue & Time: Aula Polivalente, Plaza Mayor UAM / 15:30 Abstract: The dark sector — comprising dark energy and dark matter — has remained a profound mystery for decades. In this talk, I will review this subject and show how string theory naturally leads to a predictive framework for a unified […] |

Speaker: Antonia Paraskevopoulou (Munich, Max Planck Inst. and LMU Munich) Venue & Time: Red Room / 12:00 Abstract: 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 […]

Speaker: Tarun Souradeep (Raman Research Institute, Bengaluru, India) Venue & Time: Red Room / 3:00 PM Abstract: 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 […] |

Speaker: Alexander Zlokapa (MIT) Venue & Time: Red Room / 11:30 Abstract: 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, […] |

Speaker: Fien Apers (IFT) Venue & Time: Red Room / 12:00 Abstract: 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 […]

Speaker: Roberto Vega-Morales Venue&Time: Red Room / 15:00 Abstract: 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.
