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 […] 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.

The IBS-IFT Workshop is a regular event organized jointly by IFT and IBS-CTPU, this year reaching its tenth anniversary. The aim of the workshop is share ideas, foster collaborations, and to discuss recent developments in theoretical physics. The event is organized over two weeks. The first week, November 4-7, will focus on String Phenomenology The Center […]

Speaker: Sounak Pal (Indian Institute of Technology) Venue&Time: Grey Room 3 / 11:30 Abstract: I will discuss some aspects of 2D and 3D quantum gravity in the language of Topological quantum field theory (TQFT). Recent developments include calculating various gravity partition functions in AdS3 using descriptions of Liouville conformal field theory (CFT). We extend this […]

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: 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: Miguel Zumalacárregui from Max Planck Institute for Gravitational Physics (Albert Einstein Institute). Venue&Time: Red Room / 3:00 PM Abstract: 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 […] |

Speaker: Suraj Prakash, IFIC (Valencia) Venue&Time: Red Room / 3:00 PM Abstract: 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 […] |
