-periodic dissipationless ac Josephson effect on a quantum spin-Hall edge via a Quantum magnetic impurity
Hoi-Yin Hui, Jay D. Sau
Time-reversal invariance places strong constraints on the properties of the quantum spin Hall edge. One such restriction is the inevitability of dissipation in a Josephson junction…
Proximity-induced superconductivity and Josephson critical current in quantum spin Hall systems
Hoi-Yin Hui, Alejandro M. Lobos, Jay D. Sau +1
We consider recent experiments on wide superconductor-quantum spin Hall insulator (QSHI)-superconductor Josephson junctions, which have shown preliminary evidence of proximity-indu…
Majorana fermions in ferromagnetic chains on the surface of bulk spin-orbit coupled -wave superconductors
Hoi-Yin Hui, P. M. R. Brydon, Jay D. Sau +2
Majorana fermion (MF) excitations in solid state system have non-Abelian statistics which is essential for topological quantum computation. Previous proposals to realize MF, howeve…
Topological Yu-Shiba-Rusinov chain from spin-orbit coupling
P. M. R. Brydon, S. Das Sarma, Hoi-Yin Hui +1
We investigate the possibility of realizing a topological state in the impurity band formed by a chain of classical spins embedded in a two-dimensional singlet superconductor with…
Generalized Eilenberger theory for Majorana zero-mode-carrying disordered -wave superconductors
Hoi-Yin Hui, Jay D. Sau, S. Das Sarma
Disorder is known to suppress the gap of a topological superconducting state that would support non-Abelian Majorana zero modes. In this paper, we study using the self-consistent B…
