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…
Chiral edge mode for single-cone Dirac fermions
C. W. J. Beenakker
We study the appearance of a chiral edge mode on the two-dimensional (2D) surface of a 3D topological insulator (TI). The edge mode appears along the 1D boundary with a magnetic in…
Topologically protected Casimir effect for lattice fermions
C. W. J. Beenakker
The electromagnetic Casimir effect has a fermionic counterpart in topological insulators: Zero-point fluctuations of a massless Dirac fermion field mediate a force between magnetic…
Helical Luttinger liquid on a space-time lattice
V. A. Zakharov, J. Tworzydlo, C. W. J. Beenakker +1
The Luttinger model is a paradigm for the breakdown due to interactions of the Fermi liquid description of one-dimensional massless Dirac fermions. Attempts to discretize the model…
