The Non-Dissipative Spin-Hall Current
D. Schmeltzer
A theory based on the Aharonov -Bohm effect in the momentum space for the Spin-Hall conductivity without a magnetic field is presented. The two dimensional Rashba Hamiltonian is di…

Z_2 Gauge Theory of Electron Fractionalization in the t,t'-J Model
D. Schmeltzer, A. R. Bishop
We consider a strongly correlated "t,t'-J" spin model with a positive uniaxial anisotropy. We show that in 2+1 dimensions, this model is equivalent to spin-charge excitations coupl…
