An Analytical Solution of the Schrödinger Equation for H_2^+ Molecular ion for n = 0, 1 and 2: The Born-Oppenheimer Approximation

Hydrogen molecular ion H_2^+ is generally accepted as the simplest molecule. On the other hand, the Born-Oppenheimer approximation is almost invariably the mandatory one starting point for the quantum-mechanical treatment of molecular systems. It consists of the separation of the electronic and nuclear degrees of freedom which is possible because of the enormous difference between […]

Quantum mechanical treatment of Shannon entropy measure and energy spectra of selected diatomic molecules with the modified Kratzer plus generalized inverse quadratic Yukawa potential model

In this research, we have obtained the energy eigenvalues and the corresponding normalized eigenfunction for the linear combination of the modified Kratzer and generalized inverse quadratic Yukawa potential using two different analytical methods: the exact quantization rule and the formula method respectively. The obtained normalized wave function is used to study the Shannon entropy in […]

Magnetic susceptibility and Magnetocaloric effect of Frost-Musulin potential subjected to Magnetic and Aharonov-Bohm (Flux) fields for CO and NO diatomic molecules

In this paper, we perform a nonrelativistic study of Frost-Musulin potential (FMP) impacted by the external magnetic and AB flux fields for the CO and NO diatomic molecules using the Nikiforov-Uvarov method with the Greene-Aldrich approximation to the centrifugal barrier. The numerical computation of the proposed potential reveals that the combined impact of the magnetic […]

Eigensolutions of the Schrödinger equation with a class of Yukawa potentials via supersymmetric approach

Abstract Using the basic concept of the supersymmetric shape invariance approach and formalism, we obtained an approximate solution of the Schrödinger equation with an interaction of inversely quadratic Yukawa potential, Yukawa potential and Coulomb potential which we considered as a class of Yukawa potentials. By varying the potential strengths, we obtained a solution for Hellmann […]

A new Coulomb ring-shaped potential via generalized parametric Nikiforov-Uvarov method

AbstractIn this paper, the Schrödinger equation is analytically solved for the Coulomb potential with a novel angle-dependent part. The generalized parametric Nikiforov-Uvarov method is used to obtain energy eigenvalues and corresponding eigenfunctions. We presented the effect of the angle-dependent part on radial solutions and some special cases are also discussed.  

Optimized basis expansion as an extremely accurate technique for solving time-independent Schrödinger equation

AbstractWe use the optimized trigonometric finite basis method to find energy eigenvalues and eigenfunctions of the time-independent Schrödinger equation with high accuracy. We apply this method to the quartic anharmonic oscillator and the harmonic oscillator perturbed by a trigonometric anharmonic term as not exactly solvable cases and obtain the nearly exact solutions.    

Characteristics of charged pions in the quark model with potential which is the sum of the Coulomb and oscillator potential

AbstractIn this paper, we calculate the polarizability of the charged pions in the nonrelativistic quark potential model.
