Majorana-metal transition in a disordered superconductor: percolation in a landscape of topological domain walls
V. A. Zakharov, I. C. Fulga, G. Lemut +2
Most superconductors are thermal insulators. A disordered chiral -wave superconductor, however, can make a transition to a thermal metal phase. Because heat is then tra…
Dynamical simulation of the injection of vortices into a Majorana edge mode
I. M. Flór, A. Donís-Vela, C. W. J. Beenakker +1
The chiral edge modes of a topological superconductor can transport fermionic quasiparticles, with Abelian exchange statistics, but they can also transport non-Abelian anyons: Edge…
Tangent fermions: Dirac or Majorana fermions on a lattice without fermion doubling
C. W. J. Beenakker, A. Donis Vela, G. Lemut +2
I. Introduction II. Two-dimensional lattice fermions III. Methods to avoid fermion doubling (sine dispersion, sine plus cosine dispersion, staggered lattice dispersion, linear sawt…
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…
