A generalization of the concept of PT symmetry
نویسنده
چکیده
Abstract We show that the PT symmetric Hamiltonians (and their generalizations H = H defined in the text) may be all assigned the projected (so called Feshbach or effective) nonlinear Hamiltonians which are “locally” Hermitian. This implies that many (if not all) of the bound-state energies may be real in a broad domain of Hermiticityviolating interactions. A complexification of a superintegrable D = 2 example is conjectured as an illustration.

Quantum toboggans: models exhibiting a multisheeted PT −symmetry
A generalization of the concept of PT −symmetric Hamiltonians H = p + V (x) is presented. For the usual analytic potentials V (x) (with singularities) and for the recently widely accepted “PT −symmetric” asymptotic boundary conditions for wave functions ψ(x) (selected inside a pair of complex wedges generalizing the usual x → ±∞ asymptotics), non-equivalent quantum toboggans are defined as inte...
متن کاملNumerical Analysis of Stability for Temporal Bright Solitons in a PT-Symmetric NLDC
PT-Symmetry is one of the interesting topics in quantum mechanics and optics. One of the demonstration of PT-Symmetric effects in optics is appeared in the nonlinear directional coupler (NLDC). In the paper we numerically investigate the stability of temporal bright solitons propagate in a PT-Symmetric NLDC by considering gain in bar and loss in cross. By using the analytical solutions of pertu...
متن کاملA Discussion on Concept of Symmetry snd Asymmetry
This paper is concerned about the concept os asymmetry. The different types of asymmetry for univariate and multivariate distributions have introduces been considered as well as some of usual asymmetry criteria. A brief overview of method for adding the capability of modeling asymmetry to a symmetry distribution is also a secondary purpose of this paper.
متن کاملQuantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure
We investigate the medium effect of a parity-time (PT)-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature (T=0 K). To do so, we use the canonical quantization approach and describe the amplification and dissipation properties of the constituent layers of the bilayer structure by Lorentz model to analyze the quadrature squeezing of the outgoing ...
متن کاملEffect of Relative Phase on the Stability of Temporal Bright Solitons in a PT- Symmetric NLDC
In this paper we numerically investigate the effect of relative phase on thestability of temporal bright solitons in a Nano PT- Symmetric nonlinear directionalcoupler (NLDC) by considering gain in bar and loss in cross. We also study the effect ofrelative phase on the output perturbed bright solitons energies, in the range of 0 to 180 . By using perturbation theory three eigenfunctions an...
