[Journal Club] Bootstrapping Pions at Large N

Abstract: For this journal club meeting I will comment on a recent paper by Albert and Rastelli (https://arxiv.org/abs/2203.11950) in which they apply modern S-matrix bootstrap techniques to the old problem […]

DM indirect searches with cosmic-ray antiparticles

Auditorium (LAPTh)

Speakers: Pedro de la Torre Luque (Stockholm University)The creation of antiparticles in the Galaxy has been discussed as a potential signal of exotic production mechanisms such as primordial black hole evaporation or dark matter decay/annihilation, in addition to the more conventional production from cosmic-ray (CR) interactions. Recent CR detectors have provided very accurate measurements on […]

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. […]
