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

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.

Automated summary

In this study, we investigate the few-body dynamics of dipolar bosons in one-dimensional double-wells, exploring phenomena such as tunneling oscillations, self-trapping, and equilibrium behavior. The dynamics of two-body correlations is found to be strongly influenced by both the non-local nature of repulsion and inter-well coherence, and is linked to the occupation of natural orbitals of the one-body density matrix.
