Andreev reflection mediated by topological corner states in a two-dimensional honeycomb lattice
Kai-Tong Wang, Yunjin Yu, Fuming Xu +1
Topological corner states in two-dimensional second-order topological insulators (SOTIs) are localized in real space. We numerically demonstrate that such localized topological cor…
Universal behavior of magnon-mediated spin transport in disordered NM/NM/FI heterostructure
