Solution of the Dirac equation for pseudoharmonic potential by using the Nikiforov–Uvarov method

Physica Scripta, 2009
We investigate the energy spectra and corresponding wave functions of the Dirac equation for pseudoharmonic potential with spin and pseudospin symmetry. To obtain an analytical solution of the Dirac equation, we consider the Nikiforov–Uvarov method in the calculations.

WKB Energy Expression for the Radial Schrödinger Equation with a Generalized Pseudoharmonic Potential

Asian Journal of Physical and Chemical Sciences, 2020
In this paper, we applied the semi-classical quantization approximation method to solve the radial Schrödinger equation with a generalized Pseudoharmonic potential. The four turning points problem within the framework of the Wentzel-Kramers-Brillouin (WKB) method was transformed into two turning points and subsequently, the energy spectrum was obtained.

Approximate Solutions of Schrodinger Equation with Some Diatomic Molecular Interactions Using Nikiforov‐Uvarov Method

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We used a tool of conventional Nikiforov‐Uvarov method to determine bound state solutions of Schrodinger equation with quantum interaction potential called Hulthen‐Yukawa inversely quadratic potential (HYIQP). We obtained the energy eigenvalues and the total normalized wave function.

Relativistic Energy Analysis of Five‐Dimensional q‐Deformed Radial Rosen‐Morse Potential Combined with q‐Deformed Trigonometric Scarf Noncentral Potential Using Asymptotic Iteration Method

Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
We study the exact solution of Dirac equation in the hyperspherical coordinate under influence of separable q‐deformed quantum potentials. The q‐deformed hyperbolic Rosen‐Morse potential is perturbed by q‐deformed noncentral trigonometric Scarf potentials, where all of them can be solved by using Asymptotic Iteration Method (AIM).

Exact Pseudospin Symmetric Solution of the Dirac Equation for Pseudoharmonic Potential in the Presence of Tensor Potential

Few-Body Systems, 2010
Under the pseudospin symmetry, we obtain exact solution of the Dirac equation for the pseudoharmonic potential in the presence of the tensor potential with arbitrary spin–orbit coupling quantum number κ. The energy eigenvalue equation of the Dirac particles is found and the corresponding radial wave functions are presented in terms of confluent ...

Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
We study approximate analytical solutions of the Dirac equation with the trigonometric Pöschl‐Teller (tPT) potential and a Coulomb‐like tensor potential for arbitrary spin‐orbit quantum number κ under the presence of exact spin and pseudospin (p‐spin) symmetries.
