We investigate the resonant quantum dynamics of a laser-pumped real or
artificial two-level single-atom system embedded in a leaking microcavity. We
found that for stronger laser-atom-cavity couplings the generated microcavity
photons exhibit larger steady-state correlations. In particular, the second-
and third-order photon correlation functions are greater than the corresponding
ones obtained for an incoherent light source, respectively. Furthermore, the
emitted microcavity photon flux is enhanced in comparison to weaker coupling
cases.Comment: 6 pages, 5 figure
The entanglement dynamics of a laser-pumped two-level quantum dot pair is investigated in the steady-state. The closely spaced two-level emitters, embedded in a semiconductor substrate, interact with both the environmental vacuum modes of the electromagnetic field reservoir as well as with the lattice vibrational phonon thermostat. We have found that the entanglement among the pair's components is substantially enhanced due to presence of the phonon subsystem. The reason is phonon induced decay among the symmetrical and antisymmetrical two-qubit collective states and, consequently, the population of the latter one. This also means that through thermal phonon bath engineering one can access the subradiant two-particle cooperative state.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
