Annular Majorana mode in a superconducting topological insulator
Shengshan Qin, Chi Wu, Lun-hui Hu +2
When the surface states of a topological insulator becomes superconducting, topological superconductivity can be obtained, and each vortex on the surface can host one single Majora…

Robust topological superconductivity in spin-orbit coupled systems at higher-order van Hove filling
Xinloong Han, Jun Zhan, Fu-chun Zhang +2
Van Hove singularities (VHSs) in proximity to the Fermi level promote electronic interactions and generate diverse competing instabilities. It is also known that a nontrivial Berry…
