Show affiliationsThe existence of a symmetry of the Dirac equation for a massless particle in a scalar field is demonstrated, and its effect on the bandstructure of certain arrays of scalar delta -function potentials is investigated. The implications of the symmetry for more general scalar potentials are also discussed.
