Topological superconductivity in the extended Kitaev-Heisenberg model
Johann Schmidt, Daniel D. Scherer, Annica M. Black-Schaffer
We study superconducting pairing in the doped Kitaev-Heisenberg model by taking into account the recently proposed symmetric off-diagonal exchange . By performing a mean-field a…
Bulk topology of line-nodal structures protected by space group symmetries in class AI
Adrien Bouhon, Annica M. Black-Schaffer
We give an exhaustive characterization of the topology of band structures in class AI, using nonsymmorphic space group 33 () as a representative example where a great varie…
Multiple odd-frequency superconducting states in buckled quantum spin Hall insulators with time-reversal symmetry
Dushko Kuzmanovski, Annica M. Black-Schaffer
We consider a buckled quantum spin Hall insulator (QSHI), such as silicene, proximity-coupled to a conventional spin-singlet, s-wave superconductor. Even limiting the discussion to…
Odd-frequency superconducting pairing and subgap density of states at the edge of a two-dimensional topological insulator without magnetism
Jorge Cayao, Annica M. Black-Schaffer
We investigate the emergence and consequences of odd-frequency spin-triplet s-wave pairing in superconducting hybrid junctions at the edge of a two-dimensional topological insulato…
Majorana splitting from critical currents in Josephson junctions
Jorge Cayao, Pablo San-Jose, Annica Black-Schaffer +2
A semiconducting nanowire with strong Rashba spin-orbit coupling and coupled to a superconductor can be tuned by an external Zeeman field into a topological phase with Majorana zer…
