Title: 'Asymmetric Dark Matter induced by Baryogenesis' Speaker: Miguel Escudero (CERN) Venue&Time: Red Room / 15:00 Abstract: We live in a Universe where structures are made out of baryons but not of antibaryons. Could the dark matter be made of particles and not antiparticles? This is an old question and many asymmetric dark matter scenarios […] |

Speaker: Shunsuke Neda (ICRR, Univ. of Tokyo) Venue & Time: Red Room / 15:00 Title: Primordial black holes from Q-balls Abstract: We discuss primordial black holes (PBHs) originating from Q-balls, which are non-topological solitons arising in complex scalar field theories with a global U(1) symmetry. Depending on the cosmic expansion history, Q-balls can source PBH formation in […] |

Speaker: Marta Florido Llinás (MPQ) Title: 'Generalizing the framework of translationally invariant MPS' Abstract: In this talk I will present our recent work on developing a canonical form for uniform matrix product states (MPS) with a boundary matrix (https://www.arxiv.org/abs/2512.11968). Starting from the standard canonical description of uniform MPS with periodic boundary conditions, I will explain […] |

Gravity, Supergravity and Superstrings (GRASS) Seminar Speaker: David Pereñiguez (Johns Hopkins U.) Title: 'Gravitational Duality at the Lightring, QNM isospectrality, and Ringdown Nonlinearities from Penrose Limits' Abstract: At high frequencies, the physics near a black hole’s lightring can be captured by Penrose-limit plane waves adapted to the photon sphere. In this talk, I will solve […]

Strings, Pheno and the Swampland Journal Club (SPS) Speaker: Michelangelo Tartaglia (IFT) Title: 'Anomaly-induced vanishing of brane partition functions' Abstract: 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 […] |

Title: 'The tensions of LCDM: An update of observations and theoretical implications' Speaker: Leandros Perivolaropoulos (Ioannina) Venue&Time: Red Room / 15:00 Abstract: The standard LCDM cosmological model, despite its success in describing the large-scale structure of the Universe, is currently challenged by statistically significant discrepancies between early and late-universe observations. In this talk, I provide […] |

Speaker: Suman Das (IFT) Title: 'Brick wall Normal Modes and Emerging Thermality' Venue & Time: Gray Room 1 / 11:00 Abstract: arXiv:2401.01417 The ’t Hooft brick wall model provides one of the earliest microscopic derivations of the black-hole area law within the probe approximation of quantum field theory in curved spacetime. In this talk, I […] |

As part of the 4º ESO + Empresa educational programme, the Instituto de Física Teórica (IFT) will host a group of secondary-school students from 23 to 26 March. During their stay, students will participate in a series of outreach and educational activities designed to provide a general introduction to theoretical physics research and the day-to-day […] |
