A Topological Spin Chern Pump
C. Q. Zhou, Y. F. Zhang, L. Sheng +3
We propose a one-dimensional electron model with parameters modulated adiabatically in closed cycles, which can continuously pump spin to leads. By defining the spin-polarized Wann…

Entanglement, subsystem particle numbers and topology in free fermion systems
Y. F. Zhang, L. Sheng, R. Shen +2
We study the relationship between bipartite entanglement, subsystem particle number and topology in a half-filled free fermion system. It is proposed that the spin-projected partic…
