Solutions of the Schrodinger equation for pseudo-Coulomb potential plus a new improved ring-shaped potential in the cosmic string space-time

摘要

In this paper, we obtain the bound state energy eigenvalues and the corresponding eigenfunctions of the Schrodinger equation for the pseudo-Coulomb potential plus a new improved ring-shaped potential within the framework of cosmic string space-time using the generalized parametric Nikiforov-Uvarov method. Our results are in good agreement with other works in the cosmic string space-time and reduced to those in the Minkowski space-time when alpha = 1.
