Collective excitations of a strongly-correlated non-equilibrium photon fluid across the Mott/superfluid phase transition
Fabio Caleffi, Massimo Capone, Iacopo Carusotto
We develop a Gutzwiller theory for the non-equilibrium steady states of a strongly-interacting photon fluid driven by a non-Markovian incoherent pump. In particular, we explore the…

Impurity dephasing in a Bose-Hubbard model
Fabio Caleffi, Massimo Capone, Inés de Vega +1
We study the dynamics of a two-level impurity embedded in a two-dimensional Bose-Hubbard model at zero temperature from an open quantum system perspective. Results for the decohere…
