Ballistic dynamics of Dirac particles in electro-magnetic fields
Josef Mehringer, Edgardo Stockmeyer
Investigating properties of two-dimensional Dirac operators coupled to an electric and a magnetic field (perpendicular to the plane) requires in general unbounded (vector-) potenti…

On the essential spectrum of two-dimensional Pauli operators with repulsive potentials
Josef Mehringer
We investigate the spectrum of the two-dimensional Pauli operator, describing a spin- particle in a magnetic field , with a negative scalar potential such that gr…
