Quantum correlations in dissipative gain-loss systems across exceptional points
Federico Roccati, Archak Purkayastha, G. Massimo Palma +1
We investigate the behavior of correlations dynamics in a dissipative gain-loss system. First, we consider a setup made of two coupled lossy oscillators, with one of them subject t…
The meaning of redundancy and consensus in quantum objectivity
Diana A. Chisholm, Luca Innocenti, G. Massimo Palma
While the terms "redundancy" and "consensus" are often used as synonyms in the context of quantum objectivity, we show here that these should be understood as two related but disti…
Non-Hermitian physics and master equations
Federico Roccati, G. Massimo Palma, Fabio Bagarello +1
A longstanding tool to characterize the evolution of open Markovian quantum systems is the GKSL (Gorini-Kossakowski-Sudarshan-Lindblad) master equation. However, in some cases, ope…
