Conceptual Aspects of PT-Symmetry and Pseudo-Hermiticity: A status report
Ali Mostafazadeh
We survey some of the main conceptual developments in the study of PT-symmetric and pseudo-Hermitian Hamiltonian operators that have taken place during the past ten years or so. We…
Survival probability in a one-dimensional quantum walk on a trapped lattice
Meltem Gonulol, Ekrem Aydiner, Yutaka Shikano +1
The dynamics of the survival probability of quantum walkers on a one-dimensional lattice with random distribution of absorbing immobile traps are investigated. The survival probabi…
Quantum Coherence and Correlations of optical radiation by atomic ensembles interacting with a two-level atom in microwave cavity
Ö. E. Müstecaplıoğlu
We examine quantum statistics of optical photons emitted from atomic ensembles which are classically driven and simultaneously coupled to a two-level atom via microwave photon exch…
Pseudo-Hermiticity and Electromagnetic Wave Propagation: The case of anisotropic and lossy media
A. Mostafazadeh, G. Scolarici
Pseudo-Hermitian operators can be used in modeling electromagnetic wave propagation in stationary lossless media. We extend this method to a class of non-dispersive anisotropic med…
Application of Pseudo-Hermitian Quantum Mechanics to a Complex Scattering Potential with Point Interactions
Hossein Mehri-Dehnavi, Ali Mostafazadeh, Ahmet Batal
We present a generalization of the perturbative construction of the metric operator for non-Hermitian Hamiltonians with more than one perturbation parameter. We use this method to…
Pseudo-Hermiticity and Electromagnetic Wave Propagation in Dispersive Media
Ali Mostafazadeh
Pseudo-Hermitian operators appear in the solution of Maxwell's equations for stationary non-dispersive media with arbitrary (space-dependent) permittivity and permeability tensors.…
