Pole expansion of self-energy and interaction effect on topological insulators
Lei Wang, Hua Jiang, Xi Dai +1
We study effect of interactions on time-reversal-invariant topological insulators. Their topological indices are expressed by interacting Green's functions. Under the local self-en…

Frequency domain winding number and interaction effect on topological insulators
Lei Wang, Xi Dai, X. C. Xie
We study the effect of interactions on the time reversal invariant topological insulators in four and three spatial dimensions. Their topological indices are expressed by the inter…

Quantum Spinon Oscillations
Zi Cai, Lei Wang, X. C. Xie +4
The full quantum dynamics of a spinon under external magnetic fields is investigated by using the time-evolving block decimation (TEBD) method within the microcanonical picture of…
