Abstract
The evolution of mode entanglement is analysed for a system of two indistinguishable bosons with two accessible modes. Whereas entanglement remains stationary whenever the number of bosons in each mode is left invariant, it exhibits a rich dynamics under the effects of single- and two-particle tunneling. By analysing such effects in paradigmatic families of states, our results provide guidance for the design and control of specific dynamics of mode entanglement, by varying the tunneling transition rates and the preparation of the initial state.
Mode-entanglement dynamics is analyzed for two bosons that hop between two sites. Qualitatively different dynamics are observed for different tunneling rates regimes. Evolution towards orthogonality reflects in a regular dynamics of entanglement. Specific controlled dynamics can be achieved by appropriate tunneling rates
