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…
Discovery of a nonsymmorphic superconductor with spontaneous rotational symmetry breaking and nontrivial zero modes
Hui Guo, Zhixuan Li, Senhao Lv +13
Topological superconductivity has attracted great interest due to its fundamental significance for realizing Majorana quasiparticles and fault-tolerant quantum computation. Nonsymm…
Interband pairing as the origin of the sublattice dichotomy in monolayer FeSe/SrTiO_3
Zhipeng Xu, Shengshan Qin, Kun Jiang +1
Sublattice dichotomy in monolayer FeSe/SrTiO, signaling the breaking of symmetries exchanging the two Fe sublattices, has recently been reported. We propose that interband pair…
Interband-Pairing-Boosted Supercurrent Diode Effect in Multiband Superconductors
Jiong Mei, Shengshan Qin, Jiangping Hu
We unveil a mechanism that enables a robust supercurrent diode effect in Josephson junctions based on multiband superconductors. We predict that interband pairing can significantly…
Double Majorana Vortex Flat Bands in the Topological Dirac Superconductor
Zhongyi Zhang, Zixi Fang, Shengshan Qin +3
Vortex lines, known as topological defects, are cable of trapping Majorana modes in superconducting topological materials. Previous studies have primarily focused on topological ba…
Observation of Majorana zero modes emerged from topological Dirac semimetal states under uniaxial strain
Quanxin Hu, Shengshan Qin, Yi Peng +12
The topological properties observed in iron-based superconductors extend our understanding of vortex Majorana quasiparticle excitations in unexpected ways. Vortex Majorana physics…
