Strings, Pheno and the Swampland (SPS) Journal Club Speaker: Gonzalo F. Casas (IFT) Title: 'Axion-Scalar Systems and Dynamical Distances' Abstract: We study the cosmology of axion-scalar pairs, coupled by a hyperbolic field-space metric and with a string-motivated rational scalar potential. Borrowing tools from the theory of dynamical systems, we are able to classify all late-time […]
Title: 'Beyond the Minimal Axion: Robustness of Standard Predictions' Speaker: Sung Mook Lee (CERN) Venue & Time: Red Room / 15:00 Abstract: The QCD axion is one of the most compelling candidates for physics beyond the Standard Model, as it can simultaneously solve the strong CP problem and account for the dark matter abundance. In the minimal […]
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 […]
Title: 'Observing Quantum Gravity in Extremely Cold Horizons' Speaker: Roberto Emparan (Universidad de Barcelona) Venue&Time: Red Room / 15:00 Abstract: Recent developments have revealed that black holes near extremality exhibit large quantum fluctuations in their geometry, marking a controllable breakdown of semiclassical quantum field theory in curved spacetime. In this talk, I will discuss how […]
Every Tuesday at 2:00 PM in the discussion room on the 5th floor. Join the IFT cosmology/gravity journal club at benty-fields.com to vote for papers and volunteer to present them
Title: Unveiling the Universe with Gravitational Waves: a Machine Learning approach Venue & Time: Blue Room / 10:30 Abstract: This thesis is devoted to the study of gravitational waves, combining theoretical investigations with novel applications of machine learning. The first part of the work addresses the dynamics of hyperbolic encounters, a class of transient gravitational […]
Title: 'QCD critical point and the predictable randomness of relativistic fluids' Speaker: Misha A. Stephanov (Illinois U., Chicago) Venue&Time: 12:00 / Red Room Abstract: Quantum Chromodynamics predicts a variety of unusual states of matter in which relativity and quantum many-body physics strongly intertwine. Discovering phase transitions between these extreme forms of matter in a laboratory […]
Speaker: Pablo Páez-Velasco (Universidad Complutense de Madrid) Venue & Time: Gray Room 2 / 14:30 Abstract: Given some sufficiently smooth, generally non-convex, function F on a Riemannian manifold, and a fixed inverse temperature, the problem of sampling with respect to the associated Gibbs distribution has played a central role in several areas, such as statistical […]
Every Thursday at 12:00 in Grey Room 2. Marta Fuentes (IFT), will present "Powerful Yukawas". We introduce a class of models where the masses of the light Standard Model fermions are due to an Effective Field Theory operator that appears beyond dimension-4 in the power counting expansion, resulting in a `Powerful Yukawa'. The effective Yukawa […]
Strings, Pheno & The Swampland Journal Club | Every Thursday at 12:00 in the Red Room. Speaker: Salvatore Raucci (IFT) Title: 'M-theory on S^1 \vee S^1 as Type 0A' Abstract: We propose an exotic geometric M-theory dual for the weak coupling Type 0A string: compactification on a sub-Planckian S^1 \vee S^1 (two circles connected at […]
