Bloch oscillations of strongly interacting Bose atoms

TL;DR

This paper investigates how residual interactions influence Bloch oscillations of strongly interacting Bose atoms, revealing that these interactions cause modulations dependent on the static force's magnitude, extending beyond the hard-core bosons model.

Contribution

The study demonstrates the effects of residual interactions on Bloch oscillations, providing insights beyond the traditional hard-core bosons approximation.

Findings

Residual interactions modulate Bloch oscillations.

Modulation patterns depend on the static force magnitude.

Analysis extends understanding beyond the hard-core bosons model.

Abstract

We analyse Bloch oscillations (i.e., oscillations induced by a static force) of strongly interacting Bose atoms {\em beyond} the hard-core bosons model. It is shown that residual interactions between the atoms modulate Bloch oscillations, where the type of modulations depends on the magnitude of the static force.
