摘要

The modified spin-wave (MSW) theory and SU(N) Schwinger boson theory (SBW) are employed to study the quantum entanglement in one- (1D) and two-dimensional (2D) Heisenberg antiferromagnets with Dzyaloshinskii-Moriya (DM) interaction which are models to superconducting materials of high critical temperature T-c such as La2CuO4. For the 1D case, we consider integer spin and for 2D case, since the behavior is independent on the spin value, we consider the one-half-spin and square lattice. We get the entanglement entropy in function of the temperature T where we have not gotten large variation of the quantum entanglement with the changing of the anisotropy and DM interaction constant D.
