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 […] |

Strings Pheno and the Swampland Journal Club: 'Self-gravitational Effects in the Black Hole-Tower Correspondence' Venue&Time: Red Room / 12:00 Speaker: Miquel Aparici (IFT) Abstract: It is well-known that in weak coupling and near decompactification limits, towers of light particles appear in the spectrum of gravitational theories. These towers can be postulated to correspond to minimal […] |

Title: 'How string theory computes quantum gravity amplitudes' Speaker: Lorenz Eberhardt (U. Amsterdam) Venue&Time: Red Room / 15:00 Abstract: String theory provides a framework in which quantum gravitational scattering amplitudes are ultraviolet finite and computable in perturbation theory. These amplitudes are defined by integrating over the moduli space of Riemann surfaces, replacing the Feynman diagram […] |
