Abstract:
We consider two identical and noninteracting harmonic oscillators coupled to either two independent bosonic
baths or to a common bosonic bath. Under the only assumption, weak coupling, we analyze in detail the
non-Markovian short-time-scale evolution of intensity correlations, entanglement, and quantum discord for
initial two-mode squeezed-thermal vacuum states. In the independent reservoirs case, we observe the detrimental
effect of the environment for all these quantities and we establish a hierarchy for their robustness against the
environmental noise. In the common reservoir case, for initial uncorrelated states, we find that only quantum
discord can be created via interaction with the bath, while entanglement and subshot noise intensity correlations
remain absent.
