Probing topological degeneracy on a torus using superconducting altermagnets
Tsz Fung Heung, Marcel Franz
The notion of topological order (TO) can be defined through the characteristic ground state degeneracy of a system placed on a manifold with non-zero genus , such as a torus. Th…

Singlet-triplet mixed state in spin-orbital-parity coupled superconductors
Tsz Fung Heung, Yip Chun Wong
Unlike noncentrosymmetric superconductors, the effects of spin singlet- and spin triplet-pairing mixing in centrosymmetric superconductors remain ambiguous. Recently, it was experi…
