Screened Coulomb Potential

In this paper we illustrate the existence of genuine bound states for a Dirac particle interacting with a scalar screened Coulomb potential in a 1 + 1 dimension. In contrast to the bare Coulomb potential, the screened Coulomb potential can bind both spin-zero and spin-1/2 particles in the scalar prescription.

Klein Gordon Equation

One-dimensional Klein–Gordon equation with screened Coulomb potential generates genuine bound states in the scalar coupling scheme. In this article we have obtained the exact solutions of the problem. The results are compared with those of the vector coupling scheme.
