Spin-Liquid State for Two-Dimensional Heisenberg Antiferromagnets on a Triangular Lattice
Zhan-hai Dong, Shiping Feng
The spin liquid state of the antiferromagnetic Heisenberg model on a triangular lattice is studied within the self-consistent Green's function method. It is shown that the spin exc…

Universal Spin Response in Copper Oxide Materials
Shiping Feng, Zhongbing Huang
The spin response in the copper oxide materials at finite temperatures in the underdoped and optimal doped regimes is studied within the framework of the fermion-spin theory. The i…
