Helical Majorana surface states of strongly disordered topological superconductors with time-reversal symmetry
Raquel Queiroz, Andreas P. Schnyder
Noncentrosymmetric superconductors with strong spin-orbit coupling and the B phase of He are possible realizations of topological superconductors with time-reversal symmetry.…
Classification of reflection symmetry protected topological semimetals and nodal superconductors
Ching-Kai Chiu, Andreas P. Schnyder
While the topological classification of insulators, semimetals, and superconductors in terms of nonspatial symmetries is well understood, less is known about topological states pro…
Dirac Surface States and Nature of Superconductivity in Noncentrosymmetric BiPd
Zhixiang Sun, Mostafa Enayat, Ana Maldonado +6
In non-magnetic bulk materials, inversion symmetry protects the spin degeneracy. If the bulk crystal structure lacks a centre of inversion, however, spin-orbit interactions lift th…
Majorana vortex-bound states in three-dimensional nodal noncentrosymmetric superconductors
Po-Yao Chang, Shunji Matsuura, Andreas P. Schnyder +1
Noncentrosymmetric superconductors (NCSs), characterized by antisymmetric spin-orbit coupling and a mixture of spin-singlet and spin-triplet pairing components, are promising candi…
Helical spin texture of surface states in topological superconductors
P. M. R. Brydon, Andreas P. Schnyder, Carsten Timm
Surface states of topological noncentrosymmetric superconductors exhibit intricate helical spin textures, i.e., the spin orientation of the surface quasiparticles is coupled to the…
