Intrinsic decoherence in an ultracold Bose gas confined in a double-well potential

Caballero Benitez, Santiago; Romero-Rochin, V; Paredes, R


We address the intrinsic decoherence of an N-body interacting bosonic quantum fluid confined in a double-well potential in one dimension, and its effect on the transition from coherent oscillations to self-trapping regimes as a function of the interparticle interaction. Performing a full quantum approach to the N-particle system, we study the transition and the observed decoherence through the analysis of the one-particle reduced density matrix. The results are obtained by following the time...[Show more]
