Title: 'Weak Particles with a strong impact' Speaker: Aritra Gupta (Krea University, India) Venue&Time: Red Room / 15:00 Abstract: Dark matter and neutrinos are among the most elusive particles in nature, yet they play a central role in the evolution of the Universe. Their extremely weak interactions make them difficult to detect, but also allow […]

Strings, Pheno and the Swampland (SPS) Journal Club Title: Heterotic Ouroboros Speaker: Chiara Altavista (IFT) Venue&Time: Red Room / 12:00 Abstract: M-theory on {\mathbf{S}}^1\vee{\mathbf{S}}^1 has recently been proposed to yield, via quotients, ten-dimensional non-supersymmetric string theories. We revisit the construction that leads to the heterotic theories, finding a consistent set of rules that reproduces the […]

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 […]

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 […]
