Date : November 9, 2021, 16:00 CET João Penedones (EPFL, Lausanne) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Title: Towards the non-perturbative cosmological bootstrap Abstract:  I will discuss the non-perturbative bootstrap approach to Quantum Field Theory (QFT) on Anti-de Sitter, Minkowski and de Sitter spacetimes. I will argue that this approach is not yet fully understood in de Sitter space and […]

First, do the equations of relativistic hydrodynamics make sense? And second, are the long-distance, late-time predictions of classical hydrodynamics universal?

However, transitions between different topological sectors of the vacuum […]

Replica symmetry is broken at low temperatures and for […]

Abstract:  Charge separation via the Chiral Magnetic Effect is currently searched for in the data of the isobar run at RHIC. Understanding how the effect is realized in heavy ion collisions is affected by many difficulties. I […]

Polytechnique) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Title: JT gravity with defects and the Aharonov-Bohm effect Abstract:  Jackiw-Teitelboim (JT) gravity is remarkable, especially when it is defined on Euclidean negatively curved backgrounds. There is a strong evidence that if its partition function is defined as sum over all higher genus […]

Many well-known systems possess such symmetries. I will present an overview of […]

Together, these generalised global symmetry can be combined and form a larger structures known as higher-group. I will give a review of recent […]

I will describe how these methods might be used to […]
