Quantum entropy of systems described by non-Hermitian Hamiltonians
Alessandro Sergi, Konstantin G. Zloshchastiev
We study the quantum entropy of systems that are described by general non-Hermitian Hamiltonians, including those which can model the effects of sinks or sources. We generalize the…

Embedding quantum systems with a non-conserved probability in classical environments
Alessandro Sergi
Quantum systems with a non-conserved probability can be described by means of non-Hermitian Hamiltonians and non-unitary dynamics. In this paper, the case in which the degrees of f…
