Single Dirac point and helical states in a one-dimensional system
Sheng-Nan Ji, Bang-Fen Zhu, Ren-Bao Liu
Odd numbers of Dirac points and helical states can exist at edges (surfaces) of two-dimensional (three-dimensional) topological insulators. In the bulk of a one-dimensional lattice…

Optical effects of spin currents in semiconductors
Jing Wang, Sheng-Nan Ji, Bang-Fen Zhu +1
A spin current has novel linear and second-order nonlinear optical effects due to its symmetry properties. With the symmetry analysis and the eight-band microscopic calculation we…
