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…
Realization of valley-spin polarized current via parametric pump in monolayer
Kai-Tong Wang, Hui Wang, Fuming Xu +2
Monolayer is a typical valleytronic material with valley-spin locked valence bands. We numerically investigate the valley-spin polarized current in monolayer vi…
Transport features of topological corner states in honeycomb lattice with multihollow structure
Kai-Tong Wang, Fuming Xu, Bin Wang +2
Higher-order topological phase in 2-dimensional (2D) systems is characterized by in-gap corner states, which are hard to detect and utilize. We numerically investigate transport pr…
Transport Induced Dimer State from Topological Corner States
Kai-Tong Wang, Yafei Ren, Fuming Xu +2
Recently, a new type of second-order topological insulator has been theoretically proposed by introducing an in-plane Zeeman field into the Kane-Mele model in the two-dimensional h…
Evolution of individual quantum Hall edge states in the presence of disorder
Kai Tong Wang, Fuming Xu, Yanxia Xing +1
Employing the Bloch eigenmode matching approach, we numerically study the evolution of individual quantum Hall edge states with respect to disorder. As shown by the two-parameter r…
