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…

Engineering Helical Superconductors with Multiple Majorana Kramers Pairs via Higher-Order Rashba Spin-Orbit Coupling
Qi-Sheng Xu, Zi-Ming Wang, Chui-Zhen Chen +3
The momentum dependence of Rashba spin-orbit coupling (RSOC) is a key ingredient for engineering topological superconductors (TSCs), yet research has overwhelmingly focused on its…

Vortex States and Coherence Lengths in Flat-Band Superconductors
Chuang Li, Fu-Chun Zhang, Lun-Hui Hu
Superconductivity in flat-band systems, governed by quantum metric of Bloch states rather than the BCS framework, exhibits unique phenomena due to the vanishing electron group velo…
