The effects of optical polarons on qubit coherence times in a RbCl quantum dot (QD) under a pseudoharmonic potential (PHP) are theoretically investigated using Fermi’s Golden Rule and Pekar type variational method (PTVM). From this, coherence time variations are analytically driven as a function of the chemical potential (CP) of two-dimensional ...

Abstract Linear and nonlinear optical absorption coefficients and refractive index changes with the three-dimensional ring-shaped pseudoharmonic potential are theoretically investigated. The wave functions and the energy levels are obtained by using separation of variables. It is found that the optical absorption coefficients and the refractive index

Comment on ‘Analytic solutions for vibrational energy levels of the pseudoharmonic potential’
Physica Scripta, 2021Abstract We argue that the pseudoharmonic potential provides an unsuitable description of the interatomic potential-energy function of a diatomic molecule because of its wrong behaviour at origin and infinity and because it does not predict dissociation.

Analytic solutions for vibrational energy levels of the pseudoharmonic potential
Physica Scripta, 2020Abstract The non-relativistic analytic solutions of a quantum mechanical system have been calculated for the case of pseudoharmonic potential by using the Whittaker functions approach. A diatomic quantum system is placed in a Pseudoharmonic potential and perturbed by an external magnetic field. The resulting Schrodinger’s equation has

We exactly determine the eigenfunctions and eigenvalues of the Dirac equation in the presence of a pseudoharmonic potential for the pseudospin symmetry that is known to have wide applications in the field of theoretical nuclear physics. We see that the problem is simply solved using the methodology of supersymmetric quantum mechanics.

In this paper, we present exact solutions of the Dirac equation with the pseudoharmonic potential including linear as well as Coulomb-like tensor potential with arbitrary spin–orbit coupling number κ under spin and pseudospin symmetry limits. The Nikiforov–Uvarov method is used to obtain energy eigenvalues and corresponding eigenfunctions in closed ...

The exact bound state solutions of the Klein–Gordon equation and Dirac equation with scalar and vector pseudoharmonic oscillator potentials are obtained in this paper. Furthermore, we have used the supersymmetric quantum mechanics, shape invariance and alternative method to obtain the required results.

AbstractExact solutions of a pseudoharmonic oscillator and a family of isospectral potentials are investigated in spherical coordinates. The entropic moment, generalized quantum similarity index, and some quantum information measures are investigated analytically and numerically for two density functions of two quantum systems with same energy and one ...
