The topological insulator(TI)is a topologically distinct quantum state of the matter,where the spin-orbit coupling plays......

We present a general theory about electron orbital motions in topological insulators.An in-plane electric field drives s......

We study theoretically the Josephson effect in a s-wave superconductor/ time-reversal-symmetry-broken quantum spin Hall ......

High-order harmonic generation originated from zigzag graphene nanoribbons (ZGNRs) induced by intense laser pulses is in......
