Quantum correlations in -symmetric systems
Federico Roccati, Salvatore Lorenzo, G. Massimo Palma +3
We study the dynamics of correlations in a paradigmatic setup to observe -symmetric physics: a pair of coupled oscillators, one subject to a gain one to a loss. Start…

Stationary quantum correlations in a system with mean-field PT symmetry
Federico Roccati, Salvatore Lorenzo, G. Massimo Palma +1
A pair of coupled quantum harmonic oscillators, one subject to a gain one to a loss, is a paradigmatic setup to implement PT-symmetric, non-Hermitian Hamiltonians in that one such…
