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 …

A conceptual framework extending (time-independent) PT-symmetric quantum mechanics
into the time-dependent domain is presented. It is built upon a nontrivial time-dependent …

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 …

We investigate the dynamics of a general two-level based anti-parity-time (anti-PT)-
symmetric qubit and study its decoherence as well as entanglement entropy properties. We …

We demonstrate that the existence of a Hermitian time-dependent intertwining operator that
maps the non-Hermitian time-dependent energy operator to its Hermitian conjugate and its …

We present an strategy for the derivation of a time-dependent Dyson map which ensures
simultaneously the unitarity of the time evolution and the observability of the whole time …

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

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 …
