Effects of anisotropy on quantum fluctuation of a three-layer system with mutisublattice

The quantum fluctuations of a three-layer Heisenberg model with six sublattices are studied by the retarded Green＇s function method and the spin-wave theory. The effects of anisotropy on the quantum fluctuations at zero temperature are discussed. The results show that the interlayer anisotropy plays...

Description
Summary:The quantum fluctuations of a three-layer Heisenberg model with six sublattices are studied by the retarded Green＇s function method and the spin-wave theory. The effects of anisotropy on the quantum fluctuations at zero temperature are discussed. The results show that the interlayer anisotropy plays an important role in balancing the quantum competitions.
