Abstract

In this paper, we consider Dirac equation in (2 + 1)-dimensional curved spacetime in the presence of a scalar potential. It is then shown that the zero energy states are degenerate and they can be obtained when the momentum [Formula: see text] in the y direction satisfies certain constraints involving the mass parameter and the scalar potential coupling.
