General corner states in 2D SSH model with intracelluar next-nearest-neighbour hopping
Xun-Wei Xu, Yu-Zeng Li, Zheng-Fang Liu +1
We investigate corner states in a photonic two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model on a square lattice with zero gauge flux. By considering intracelluar next-nearest-…
All-electric spin transistor based on a side-gate-modulated two-dimensional topological insulator
Xianbo Xiao, Ying Liu, Zhengfang Liu +3
We propose and investigate a spin transistor device consisting of two ferromagnetic leads connected by a two-dimensional topological insulator as the channel material. It exploits…
Anisotropic Quantum Confinement Effect and Electric Control of Surface States in Dirac Semimetal Nanostructures
Xianbo Xiao, Shengyuan A. Yang, Zhengfang Liu +2
The recent discovery of Dirac semimetals represents a new achievement in our fundamental understanding of topological states of matter. Due to their topological surface states, hig…
Spin-filtering and charge- and spin-switching effects in a quantum wire with periodically attached stubs
Xianbo Xiao, Zhaoxia Chen, Zhiming Rao +2
Spin-dependent electron transport in a periodically stubbed quantum wire in the presence of Rashba spin-orbit interaction (SOI) is studied via the nonequilibrium Green's function m…
