Perturbative calculation of energy levels for the Dirac equation with generalised momenta
arXiv:1909.06311
Abstract
We analyse a modified Dirac equation based on a noncommutative structure in phase space. The noncommutative structure induces generalised momenta and contributions to the energy levels of the standard Dirac equation. Using techniques of perturbation theory, we use this approach to find the lowest order corrections to the energy levels and eigenfunctions for two linear potentials in three dimensions, one with radial dependence and another with a triangular shape along one spatial dimension. We find that the corrections due to the noncommutative contributions may be of the same order as the relativistic ones.
