Title: Bound states of the two-dimensional Dirac equation for an energy-dependent hyperbolic Scarf potential,
Abstract: We study the two-dimensional massless Dirac equation for a potential that is
allowed to depend on the energy and on one of the spatial variables. After
determining a modified orthogonality relation and norm for such systems, we
present an application involving an energy-dependent version of the hyperbolic
Scarf potential. We construct closed-form bound state solutions of the
associated Dirac equation.
