Quantum dynamics of few dipolar bosons in a double-well potential

Abstract: We study the few-body dynamics of dipolar bosons in one-dimensional double-wells. By varying the interaction strength and investigating one-body observables, in the considered few-body systems we study tunneling oscillations, self-trapping, and a regime exhibiting an equilibrating behavior. The corresponding two-body correlation dynamics exhibits a strong interplay between the interatomic correlation due to non-local nature of the repulsion and the inter-well coherence. We also study the link between the correlation dynamics and the occupation of natural orbitals of the one-body density matrix. Graphical abstract: [Figure not available: see fulltext.]
