Zeeman Coupling and Abnormal Thermal Conductivities in BSCCO Superconductors
Qiang-Hua Wang, Z. D. Wang
Using the path-integral formulation we derive microscopically a Ginzburg-Landau free energy with a Zeeman coupling between the magnetic field and the orbital angular momentum of th…

Linear spin and orbital wave theory for undoped manganites
R. Y. Gu, Shun-Qing Shen, Z. D. Wang +1
We present a linear spin and orbital wave theory to account for the spin and orbital orderings observed experimentally in undoped manganite. It is found that the anisotropy of the…
