Approximate solution of the time-dependent Kratzer plus screened Coulomb potential in Feinberg-Horodecki equation

Abstract

We obtain the quantized momentum eigenvalues, P n , together with space-like coherent eigenstates for the space-like counterpart of the Schrödinger equation, the Feinberg-Horodecki equation, with a combined Kratzer potential plus screened coulomb potential which is constructed by temporal counterpart of the spatial form of these potentials. The present work is illustrated with two special cases of the general form: the time-dependent modified Kratzer potential and the time-dependent screened Coulomb potential.
