Time correlation functions for non-Hermitian quantum systems
(American Physical Society, 2015-06-09)
We introduce a formalism for time-dependent correlation functions for systems whose evolutions are governed by non-Hermitian Hamiltonians of general type. It turns out that one can define two different types of time ...
Linear Quantum Entropy and Non-Hermitian Hamiltonians
We consider the description of open quantum systems with probability sinks (or sources) in terms of general non-Hermitian Hamiltonians. Within such a framework, we study novel possible definitions of the quantum linear ...
Quantum entropy of systems described by non-Hermitian Hamiltonians
(IOP Science, 2016-03-02)
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 von Neumann entropy to the non-Hermitian ...
