Impurity dephasing in a Bose–Hubbard model

Impurity dephasing in a Bose–Hubbard model

We study the dynamics of a two-level impurity embedded in a two-dimensional Bose–Hubbard (BH) model at zero temperature from an open quantum system perspective. Results for the decoherence across the whole phase diagram are presented, with a focus on the critical region close to the transition betwe...
