Entanglement and separability of Rokhsar-Kivelson and resonating valence-bond states

Auditorium (LAPTh)

Speakers: Gilles Parez (CRM, Montréal)Entanglement and separability are two opposite yet intertwined notions in quantum mechanics. A quantum state is said to be entangled if it is not separable, and vice versa. Quantifying how entangled two subsystems are remains a challenging problem, which has led to important insights in the context of quantum many-body systems. […]

[AnLy] Solving 3d Gravity with Virasoro TQFT

Online seminar

Speakers: Lorenz Eberhardt (Princeton, IAS)Abstract: I will explain a proposal which relates three-dimensional quantum gravity in AdS3 to a particular 3d TQFT that we refer to as ``Virasoro TQFT’'. This relation gives a precise meaning to the standard folklore that pure 3d gravity is related to two copies of SL(2,R) Chern-Simons theory. I will discuss […]

Physics at TeV Colliders and Beyond the Standard Model | PhysTeV 2023

Ecole de Physique des Houches

The "PhysTeV" series of workshops aims at pushing the frontier of fundamental Physics by bringing together theorists and experimentalists working on several aspects of phenomenology at TeV colliders and other experiments.World experts are brought together to address fundamental problems raised notably by the Higgs boson discovery, dark matter and the disappearance of antimatter in the […]

Locality and symmetry for T-Tbar and gravity

Auditorium (LAPTh)

Speakers: Ruben Monten (Cern)Holography appears to be a fundamental property of gravity. However, even in well-established models like AdS/CFT, the compatibility of this principle with the locality properties of the gravitational physics we observe remains to be completely understood. We can make progress in less than four spacetime dimensions by using special properties of the […]
