Resonant spin Hall conductance in quantum Hall systems lacking bulk and structural inversion symmetry
Shun-Qing Shen, Yun-Juan Bao, Michael Ma +2
Following a previous work [Shen, Ma, Xie and Zhang, Phys. Rev. Lett. 92, 256603 (2004)] on the resonant spin Hall effect, we present detailed calculations of the spin Hall conducta…

Elementary excitations of magnetically ordered systems with orbital degeneracy
A. Joshi, M. Ma, F. Mila +2
The Holstein-Primakoff transformation is generalized to develop a quantum flavor wave theory for spin systems with orbital degeneracy. Elementary excitations consist of spin, orbit…

Phase Transitions of the Bilayered Spin-S Heisenberg Model and Its Extension to Fractional Dimensions
Kwai-Kong Ng, Fu Chun Zhang, Michael Ma
We study the ground state and the phase transitions of the bilayered spin- antiferromagnetic Heisenberg model using the Schwinger boson mean field theory. The interplane couplin…
