Gilles Parez (Université de Montréal) Seminar LPT, 30 mai 2023, 14H, 3R1, seminar room, 3rd floor Résumé : 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… Read More »Entanglement and separability of Rokhsar-Kivelson and resonating valence-bond states . – (Gilles Parez / LPT / Seminar). – 30/05/2023, 14H

Anna Francuz (Université de Vienne) Seminar LPT, 13/06/2023, 14H, 3R1, seminar room, 3rd floor Summary : Tensor networks have already proven to be extremely useful tools in the studies of strongly correlated quantum systems. Being immune to the sign problem, they enable calculations beyond Quantum Monte Carlo and directly in the thermodynamic limit. The most… Read More »Automatic differentiation in iPEPS simulations : unravelling the black box . – (Anna Francuz / LPT / Seminar). – 13/06/2023, 14H
