Comparison and unification of non-Hermitian and Lindblad approaches with applications to open quantum optical systems
Konstantin G. Zloshchastiev, Alessandro Sergi
We compare two approaches to open quantum systems, namely, the non-Hermitian dynamics and the Lindblad master equation. In order to deal with more general dissipative phenomena, we…

Volume element structure and roton-maxon-phonon excitations in superfluid helium beyond the Gross-Pitaevskii approximation
Konstantin G. Zloshchastiev
We propose a theory which deals with the structure and interactions of volume elements in liquid helium II. The approach consists of two nested models linked via parametric space.…
