Bose-Hubbard lattice as a controllable environment for open quantum systems

> Full text via publisher
We investigate the open dynamics of an atomic impurity embedded in a one-dimensional Bose-Hubbard lattice. We derive the reduced evolution equation for the impurity and show that the Bose-Hubbard lattice behaves as a tunable engineered environment allowing to simulate both Markovian and non-Markovian dynamics in a controlled and experimentally realisable way. We demonstrate that the two phases of the environmental ground state, namely the Mott insulator and the superfluid phase, are uniquely associated to the presence or absence of memory effects, respectively. Furthermore, we provide a clear explanation of the physical mechanism responsible for the onset of non-Markovian dynamics.
