We consider a parity-deformed Jaynes–Cummings model (JCM) consisting of two identical
two-level atoms interacting with a single-mode para-Bose field in a cavity. Compared to the …

In this paper, we study a two-dimensional rotationally symmetric harmonic oscillator with
time-dependent frictional force. At the classical level, we solve the equations of motion for a …

The construction of nonlinear coherent states via a unitary displacement operator is possible
only for a few quantum-mechanical systems. In this paper, we define two non-unitary and a …

Energy levels are considered for the two-photon parity λ λ-deformed Jaynes–Cummings
model of a single two-level atom interacting with a single-mode cavity field corresponding to …

A one-parameter generalized Wigner–Heisenberg algebra (WHA) is reviewed in detail. It is
shown that WHA verifies the deformed commutation rule [x ˆ, p ˆ λ]= i (1+ 2 λ R ˆ) and also …

In this paper we define a non-unitary displacement operator, which by acting on the vacuum
state of the pseudo harmonic oscillator (PHO), generates new class of generalized coherent …

This study investigates the detection of two discrete quantum phenomena arising from the
interaction between a single two-level atom, SU (1, 1) quantum systems, and a graphene …

Following the lines of the recent papers (Ann. Phys. 362, 659670 (2015) and Mod. Phys.
Lett. A 37, 1550198 (2015)), we introduce even and odd λ λ-deformed binomial states (λ λ …

By using Wigner–Heisenberg algebra (WHA) and its Fock representation, even and odd
Wigner negative binomial states (WNBSs)| M, ξ, ν〉±W (ν= 0 corresponds to the ordinary …

Using the parity deformed Heisenberg algebra (RDHA), we first establish associated
coherent states (RDCSs) for a pseudo-harmonic oscillator (PHO) system that are defined as …
