Title: 'Probabilistic modeling and Bayesian inference for collider data' Speaker: Santiago Tanco (IFLP-CONICET/UNLP) Venue&Time: Gray Room 1 / 11:00
-
Strings, Pheno and the Swampland Journal Club Title: 'Mapping moduli across heterotic conifolds' Speaker: Christian Aoufia (IFT) Venue & Time: Red Room / 12:00 Abstract: In this work, we provide evidence for a duality between 4-dimensional Calabi-Yau compactifications of the heterotic string, in which the base manifolds are linked by a conifold transition. In recent […]

Title: 'GeV-scale QCD Axion' Speaker: Thomas Steingasser (IFT) Venue & Time: 12:00 / Gray Room 3 Abstract: In order to solve the strong CP problem, we study the possibility that the Peccei–Quinn symmetry is broken below the QCD scale. We find that a QCD axion can be above GeV, and may be among the observed […] |

Speaker: Albert Gasull, Leiden University Venue & Time: Grey Room 3 / 11:30 Title: 'Continuous and field tensor network states' Abstract: Tensor network methods have provided us with a powerful set of tools with which to study strongly interacting many-body systems on the lattice. Understanding the limitations of this ansatz is paramount for the success […] |

Sergio Rodríguez (IFT) will present "Threshold production of heavy top quarks: QCD and the Higgs boson" by Matthew J. Strassler and Michael E. Peskin. Abstract: We calculate the threshold cross section for 𝑒+𝑒−→tt¯ to leading-logarithmic order in QCD, using a nonrelativistic approximation suggested by Fadin and Khoze. We study the mass range 100≤𝑚𝑡≤250 GeV, and show […] |

Title: Holographic fluids with higher-form symmetries Speaker: André Oliveira (Heriot-Watt University) Venue & Time: Grey Room 3 / 11:30 Abstract: Higher-form symmetries are ubiquitous in physics. In this talk, I focus on the case where they are continuous and encode the conservation of extended objects. Applications include elasticity, superfluidity and phases of electromagnetism. Using holography, […]

Yuber Perez-Gonzalez (IFT) will present: 'The Cosmic Neutrino Background is within Reach of Future Neutrino Telescopes' Venue & Time: Gray Room 3 / 12:00 Abstract: The cosmic neutrino background (CνB) can be boosted to high energies due to scatterings with energetic cosmic rays (CRs) across cosmological scales. Previous calculations focused on neutral current incoherent and […]

Léo Veissière (IFT) will present: 'Hilltop quintessence, the LARGE Volume Scenario and varying-tension cosmic strings' Venue & Time: Red Room / 12:00 Recent observational data suggests that the dark energy equation of state parameter wDE is evolving with time, in apparent tension with the ΛCDM standard model of cosmology. Here we review these observational results, […]

Chuying Wang (IFT) will present 'Supersymmetry and morse theory' by Edward Witten J. DIFFERENTIAL GEOMETRY 17 (1982) 661-692 Venue & Time: Blue Room / 17:00 Abstract: It is shown that the Morse inequalities can be obtained by consideration of a certain supersymmetric quantum mechanics Hamiltonian. Some of the implications of modern ideas in mathematics […] |

Speaker: Yichao Fu (GIST) Title: Toward Krylov-based holography in double-scaled SYK Venue & Time: Gray Room 3 / 11:30 Abstract: Building on the duality between Krylov complexity and geodesic length in Jackiw-Teitelboim and sine-dilaton gravity, we develop a precise holographic dictionary for quantities in the Krylov subspace of the double-scaled Sachdev-Ye-Kitaev model (DSSYK). First, we […]

Date: Wednesday, February 18 Aula Gris 2 / 11:30 Speaker: Daniel Molpeceres (TU Munich) Título: Quantum Algorithms Based on Cooling Abstract: The purpose of this work is to study different methods for nature-inspired algorithmic cooling of physical systems, which rely on energy transfer between the system and a cool bath. These algorithms are suitable for […] |

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 (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 […]

Miquel Aparici Domingo (IFT) will present Generalized Global Symmetries by Davide Gaiotto, Anton Kapustin, Nathan Seiberg, Brian Willett, JHEP 02 (2015) 172 Abstract: A q-form global symmetry is a global symmetry for which the charged operators are of space-time dimension q, e.g. Wilson lines, surface defects, etc., and the charged excitations have q spatial dimensions, e.g. […] |
