Destruction of long-range order by quenching of the hopping range in one dimension
Destruction of long-range order by quenching of the hopping range in one dimension
We study the dynamics in a one dimensional hard-core Bose gas with power-law hopping after an abrupt reduction of the hopping range using the time-dependent density-matrix renormalization group (t-DMRG) and bosonization techniques. In particular, we focus on the destruction of the Bose-Einstein condensate (BEC), which is present in the initial …
