Temporal evolution of quantum correlations under non-Hermitian operation
In this article, we investigate the non-unitary dynamics of a two-qubit system under the action of local non-Hermitian operation from the perspectives of quantum quantum correlations under this

Features, Paradoxes and Amendments of Perturbative Non-Hermitian Quantum Mechanics
Quantum mechanics of unitary systems is considered in quasi-Hermitian representation and in the dynamical regime in which one has to take into account non-Hermitian toy models. In parallel, several paradox...

Non-Hermitian coupled cluster method for non-stationary systems and its interaction-picture reinterpretation
The interaction picture in a non-Hermitian realization is discussed in detail and considered for its practical use in many-body quantum physics. The resulting non-Hermitian interaction-picture (NHIP) descr...

The dynamical problem for a non self-adjoint Hamiltonian
We review some recent results of the so-called quasi-hermitian quantum mechanics, with particular focus on the quantum dynamics both in the Schrodinger and in the Heisenberg representations. The role of Krein space...
