FERMIONS IN AN EXTERNAL SU(2) MAGNETIC FIELD
M. H. Friedman, Y. Srivastava, A. Widom
Abstract
We consider Fermions in a constant and uniform external SU(2) magnetic field. We find that the results for the energy levels depend on the choice of gauge potential. Choosing a Landau type gauge potential yields his results. On the other hand in another gauge potential, one obtains a different continuous eigenvalue spectrum.
