Dynamical localization of Dirac particles in electromagnetic fields with dominating magnetic potentials
Jean-Marie Barbaroux, Josef Mehringer, Edgardo Stockmeyer +1
We consider two-dimensional massless Dirac operators in a radially symmetric electromagnetic field. In this case the fields may be described by one-dimensional electric and magneti…
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…
Confinement-deconfinement transitions for two-dimensional Dirac particles
Josef Mehringer, Edgardo Stockmeyer
We consider a two-dimensional massless Dirac operator coupled to a magnetic field and an electric potential growing at infinity. We find a characterization of the spectrum…
