Non-Hermitian Heisenberg representation
In a way paralleling the recently accepted non-Hermitian version of quantum mechanics in its Schrodinger representation (working often with the innovative possible to construct an analogous non-Hermitian v...

Factorized Hilbert-space metrics and non-commutative quasi-Hermitian observables
In 1992, Scholtz et ad. (Ann. Phys., 213 (1992) 74) showed that a set of non-Hermitian operators can represent observables of a closed unitary quantum system, provided only that its elements are quasi-Hermitian...

Linear representation of energy-dependent Hamiltonians
operators are non-Hermitian so that our formalism admits a natural extension to non-Hermitian initial H(E)s. Its applicability may range from pragmatic phenomenology and variational calculations (where al...

Composite Quantum Coriolis Forces
In a consistent quantum theory known as 'non-Hermitian interaction picture' (NIP), the standard quantum Coriolis operator S(t) emerges whenever the observables of a unitary system are given in their quasi-Hermi...

Problem of the coexistence of several non-Hermitian observables in PT -symmetric quantum mechanics
During recent developments in quantum theory it has been clarified that observable quantities (such as energy and position) may be represented by operators Lambda (with real spectra) that are manifestly non-Hermitian

Non-stationary quantum mechanics in hybrid non-Hermitian interaction representation

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. Interestingly, by proper tuning of the system's par...

Hermitian-Non-Hermitian Interfaces in Quantum Theory

Theory of Response to Perturbations in Non-Hermitian Systems Using Five-Hilbert-Space Reformulation of Unitary Quantum Mechanics
Non-Hermitian quantum-Hamiltonian-candidate combination H lambda of a non-Hermitian unperturbed operator H=H0 with an arbitrary 'small' non-Hermitian perturbation lambda W is given a math...
