We study the proximity effect between an s-wave superconductor and the surface states of a strong topological insulator. The resulting two-dimensional state resembles a spinless px+ipy superconductor, but does not break time reversal symmetry. This state supports Majorana bound states at vortices. We show that linear junctions between superconductors mediated by the topological insulator form a nonchiral one-dimensional wire for Majorana fermions, and that circuits formed from these junctions… Expand

Theory of the Josephson current on a magnetically doped topological insulator
Proximity induced superconducting states in the surface of magnetically doped topological insulators can host chiral Majorana modes. We consider a Josephson junction in that system with changing theExpand

Symmetry protected Josephson supercurrents in three-dimensional topological insulators.
TLDR
It is shown that the supercurrent is largely carried by surface states, due to the inherent topology of the bands, and that it is robust against disorder, which clarifies key open issues regarding the nature of supercurrents in topological insulators. Expand
Zeeman-induced gapless superconductivity with a partial Fermi surface

Minimal Zeeman field requirement for a topological transition in superconductors
Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that theExpand

Topological superconductivity and the fractional Josephson effect in quasi-one dimensional wires on a plane
A time-reversal invariant topological superconductivity is suggested to be realized in a quasi-one-dimensional structure on a plane, which is fabricated by filling the superconducting materials intoExpand

Two-Dimensional Topological Superconductivity with Antiferromagnetic Insulators.
TLDR
This proposal exploits the appearance of solitonic states at the interface between a topologically trivial antiferromagnet and a conventional superconductor, which realize a topological superconducting phase when their spectrum is gapped by intrinsic spin-orbit coupling. Expand
