Author(s): Koji Kudo, Ryota Nakai, Hiroki Isobe, J. K. Jain, and Kentaro Nomura
A two-dimensional topologically nontrivial state of noninteracting electrons, such as the surface state of a three-dimensional topological insulator, is predicted to realize a topological superconductor when proximity-coupled to an ordinary $s$-wave superconductor. In contrast, noninteracting electr… [Phys. Rev. Lett. 136, 246601] Published Tue Jun 16, 2026
