Fermion-parity anomaly of the critical supercurrent in the quantum spin-Hall effect
C. W. J. Beenakker, D. I. Pikulin, T. Hyart +2
The helical edge state of a quantum spin-Hall insulator can carry a supercurrent in equilibrium between two superconducting electrodes (separation L, coherence length xi). We calcu…
Scattering theory of topological invariants in nodal superconductors
J. P. Dahlhaus, M. Gibertini, C. W. J. Beenakker
Time-reversal invariant superconductors having nodes of vanishing excitation gap support zero-energy boundary states with topological protection. Existing expressions for the topol…
Geodesic scattering by surface deformations of a topological insulator
J. P. Dahlhaus, C. -Y. Hou, A. R. Akhmerov +1
We consider the classical ballistic dynamics of massless electrons on the conducting surface of a three-dimensional topological insulator, influenced by random variations of the su…
