Abstract: We employ a probabilistic mesoscopic description to draw conceptual and quantitative analogies between Brownian motion and late-time fluctuations of thermal correlation functions in generic chaotic systems respecting ETH. We apply this...

Abstract: I propose a bottom-up correspondence between a CFT defined on 2D non-orientable manifolds, such as the real projective plane (RP2) and the Klein bottle (K2), and AdS3 Einstein gravity with dS2 end-of-the-world branes. In this...

Abstract: The Anti-de-Sitter/Condensed Matter Theory (AdS/CMT) correspondence has attracted significant attention within high-energy physics, particularly in the study of holographic superconductors, which are modeled as asymptotically Anti-de...

Abstract: In recent years, there have been various activities trying to better understand the interplay between non-invertible global symmetries and boundary conditions in quantum field theories, with applications ranging from scattering of solitons...

Abstract: Based on https://arxiv.org/abs/2408.11139 . In this talk we'll explain how self-dual metrics (which correspond to spacetimes containing only positive helicity gravitons) can be written as a sum over connected "tree" diagrams, which are...

Abstract: Based on a recent paper with Juan and Yue-Zhou (https://arxiv.org/pdf/2409.14218). In this talk I will first review the no-boundary wavefunction in the context of inflation, and explain its natural generalization to the density matrix of a...
