Noncommutative Space Corrections on the Klein-Gordon and Dirac Oscillators Spectra (1101.2801v2)
Published 14 Jan 2011 in hep-th
Abstract: We consider the influence of a noncommutative space on the Klein-Gordon and the Dirac oscillators. The nonrelativistic limit is taken and the $\theta$-modified Hamiltonians are determined. The corrections of these Hamiltonians on the energy levels are evaluated in first-order perturbation theory. It is observed a total lifting of the degeneracy to the considered levels. Such effects are similar to the Zeeman splitting in a commutative space.
