The electron states in the quasicrystal (QC) are hot topics recently. While previous attentions were focused on such intrinsic QCs as the Penrose lattice, the recent “twistronics” provides …
We show that a two-dimensional semiconductor with Rashba spin-orbit coupling could be driven into the second-order topological superconducting phase when a mixed-pairing state …

The material realization of the intrinsic chiral topological superconductivity (TSC) is still a big challenge in modern condensed-matter physics. In this paper, we propose a general …
Recent Josephson tunneling experiments on twisted flakes of high-T c cuprate superconductor Bi 2 Sr 2 CaCu 2 O 8+ x revealed a nonreciprocal behavior of the critical …
The realization of Majorana corner modes generally requires unconventional superconducting pairing or s-wave pairing. However, the bulk nodes in unconventional …
