Time-dependent variational Monte Carlo method for interacting Bosons in continuous space — •Markus Holzmann — LPMMC, UMR 5493 of CNRS, Université Grenoble Alpes, F-38042 Grenoble, France

I will describe time-dependent Variational Monte Carlo method for continuous-space Bose systems based on a systematic truncation of the many-body wave function [1]. We have benchmarked the method by studing the Lieb-Liniger model of one dimensional Bosons interacting by a delta potential. We have calculated static ground state properties, as well as the unitary dynamics after a sudden quench in the interaction strength and compared to Bethe ansatz results wherever available.
