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 […]

Every Thursday at 12:00 in Grey Room 2.

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: '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 […]

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, […]
