Abstract

We study theoretically the dynamics of two weakly coupled Bose-Josephson junctions, prepared with the same particle number N and Josephson excitation number ν but with different reduced one-particle purity γ. An entropy oscillation mode is predicted, in which one-particle coherence is transferred between the Bose-Hubbard dimers with no particle or energy transfer. We explain this purity oscillation using a semiclassical picture.
