Method to preserve the chiral-symmetry protection of the zeroth Landau level on a two-dimensional lattice
A. Donís Vela, G. Lemut, J. Tworzydło +1
The spectrum of massless Dirac fermions on the surface of a topological insulator in a perpendicular magnetic field contains a -independent "zeroth Landau level", protected…

Reflectionless Klein tunneling of Dirac fermions: Comparison of split-operator and staggered-lattice discretization of the Dirac equation
A. Donís Vela, G. Lemut, M. J. Pacholski +2
Massless Dirac fermions in an electric field propagate along the field lines without backscattering, due to the combination of spin-momentum locking and spin conservation. This phe…

Massless Dirac fermions on a space-time lattice with a topologically protected Dirac cone
A. Donís Vela, M. J. Pacholski, G. Lemut +2
The symmetries that protect massless Dirac fermions from a gap opening may become ineffective if the Dirac equation is discretized in space and time, either because of scattering b…
