Spin Hall effect in a Doped Mott Insulator
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
The existence of conserved spin Hall currents is shown in a strongly correlated system without involving spin-orbit coupling. The spin Hall conductivity is determined by intrinsic…

Mutual-Chern-Simons effective theory of doped antiferromagnets
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
A mutual-Chern-Simons Lagrangian is derived as a minimal field theory description of the phase-string model for doped antiferromagnets. Such an effective Lagrangian is shown to ret…
