Title: 'First Order Phase Transitions and Gravitational Waves' Venue&Time: Red Room / 15:00 Speaker: Marco Finetti (U. Aveiro) Abstract: The Laser Interferometer Space Antenna (LISA) will be the first space-based gravitational wave (GW) detector, opening a new observational window for both astrophysics and early-Universe cosmology. Operating in the millihertz band, it will probe a rich […]
Title: 'Classical Krylov probes and chaotic semiclassical strings' Speaker: Saskia Demulder (CUNEF) Venue&Time: Red Room / 15:00 Abstract: Quantum chaos is a central theme in string theory, but classical chaos is also a generic feature of semiclassical string dynamics. Motivated by the need to explore the broad landscape of non-integrable string dynamics, I will introduce […]
Title: From Volume as a Clock to Boundary Dynamics in JT Gravity Speaker: Farbod-Sayyed Rassouli (University of Nottingham) Venue&Time: 11:30 / Blue Room Abstract: Different notions of time arise from different choices of observer. In cosmological settings, a particularly natural choice is the spacetime volume, which is conjugate to the cosmological constant. This leads to […]
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: ‘A diffuse flux of MeV ALPs’ Speaker: Marina Cermeño Venue&Time: Red Room / 15:00 Abstract: MeV scale axion-like particles can be produced with semi-relativistic velocities in Galactic supernovae, leading to a diffuse flux that can be detectable in neutrino water-Cherenkov detectors (Super + HyperK). In this talk, I will explain the details of the […]
Title: 'Polynomial-time thermalization and Gibbs sampling from system-bath couplings' Speaker: Sam Slezak (ENS Lyon) Venue&Time: Gray Room 3 / 11:30 Abstract: Many physical phenomena, including thermalization in open quantum systems and quantum Gibbs sampling, are modeled by Lindbladians approximating a system weakly coupled to a bath. Understanding the convergence speed of these Lindbladians to their […]
Venue&Time: Blue Room / 15:00 Coffee will be served in the cafeteria at 16:15h Title: 'Black holes, quantum entanglement, and the geometry of spacetime' Speaker: Matthew Headrick (Brandeis & IHES) Abstract: Black holes are by far the most entropic objects in the universe, and their enormous entropy directly connects the macroscopic world governed by general […]
Strings, Pheno and the Swampland (SPS) Journal Club Title: Sharpened Dynamical Cobordism Speaker: Alejandro Javier Puga Gómez (IFT) Venue&Time: Red Room / 12:00 Abstract: We propose a sharpened version of Dynamical Cobordism, where the physical structure ξ of the theory in question determines an allowed range Rξ for the critical exponent δ. We interpret a singularity with δ∈Rξ as a true transition-to-nothing, […]
Every Thursday at 12:00 in Grey Room 2.
Valeria Costa (IFT) will present: Cosmological Lower Bound on Heavy-Neutrino Masses, de B. W. Lee y S. Weinberg. Venue&Time: Blue Room / 17:00 Abstract: The present cosmic mass density of possible-stable neutral heavy leptons is calculated in a standard cosmological model. In order for this density not to exceed the upper limit of 2*10^-29 g/cm^3, […]
