Non-Hermiticity in quantum Hamiltonians leads to nonunitary time evolution and possibly
complex energy eigenvalues, which can lead to a rich phenomenology with no Hermitian …

We demonstrate that complex point transformations can be used to construct non-Hermitian
first integrals, time-dependent Dyson maps and metric operators for non-Hermitian quantum …

A non-Hermitian operator may serve as the Hamiltonian for a unitary quantum system, if we
can modify the Hilbert space of state vectors of the system so that it turns into a Hermitian …

I will provide a pedagogical introduction to non-Hermitian quantum systems that are PT-
symmetric, that is they are left invariant under a simultaneous parity transformation (P) and …

We find a different effect for the behavior of von Neumann entropy. For this we derive the
framework for describing von Neumann entropy in non-Hermitian quantum systems and …

This paper demonstrates that the parity‐time (PT PT)‐symmetric non‐Hermitian Hamiltonian
for a periodically driven system can be generated from a kernel Hamiltonian by a …

We propose time-dependent Darboux (supersymmetric) transformations that provide a
scheme for the calculation of explicitly time-dependent solvable non-Hermitian partner …

We study in this paper the time evolution of P T-symmetric non-Hermitian Hamiltonian
consisting of periodically driven SU (1, 1) generators. A non-Hermitian invariant operator is …

We provide the first solution of a time-dependent metric operator for the non-Hermitian
Jaynes–Cummings Hamiltonian. We use this solution to calculate the entanglement …

We construct a time-dependent double well potential as an exact spectral equivalent to the
explicitly time-dependent negative quartic oscillator with a time-dependent mass term …
