Many-body solitons in a one-dimensional condensate of hard core bosons

arXiv:cond-mat/0002062 · doi:10.1103/PhysRevLett.84.5691

Abstract

A mapping theorem leading to exact many-body dynamics of impenetrable bosons in one dimension reveals dark and gray soliton-like structures in a toroidal trap which is phase-imprinted. On long time scales revivals appear that are beyond the usual mean-field theory.
