Photon Propagation through Linearly Active Dimers

Photon Propagation through Linearly Active Dimers

We provide an analytic propagator for non-Hermitian dimers showing linear gain or losses in the quantum regime. In particular, we focus on experimentally feasible realizations of the PT -symmetric dimer and provide their mean photon number and second order two-point correlation. We study the pr...
