Abstract

We analyse a modified Dirac equation based on a noncommutative structure in\nphase space. The noncommutative structure induces generalised momenta and\ncontributions to the energy levels of the standard Dirac equation. Using\ntechniques of perturbation theory, we use this approach to find the lowest\norder corrections to the energy levels and eigenfunctions for two linear\npotentials in three dimensions, one with radial dependence and another with a\ntriangular shape along one spatial dimension. We find that the corrections due\nto the noncommutative contributions may be of the same order as the\nrelativistic ones.\n
