Abstract

We investigate the steady-state phase diagram of the dissipative spin-1/2 XYZ model on a two-dimensional triangular lattice, in which each site is coupled to a local environment. By means of cluster mean-field approximation, we find that the steady-state phases of the system is rather rich, in particular there exists various types of nonuniform antiferromagnetic phases due to the geometrical frustration. As the short-ranges correlations included in the analysis, we rule out the oscillatory phase and confirm the existence of triantiferromagnetic and biantiferromagnetic phases in the thermodynamic limit. Moreover, the existence of spin-density-wave phase, which is missed by the single-site mean-field analysis, is also revealed by spin-structure factor.
几何受挫耗散XYZ模型中的非均匀相位
我们研究了二维三角形晶格上耗散自旋-1/2 XYZ模型的稳态相图,其中每个位置与局部环境耦合。通过簇平均场近似,我们发现系统的稳态相相当丰富,特别是由于几何挫折,存在各种类型的非均匀反铁磁相。由于分析中包含的短程相关,我们排除了振荡相,并在热力学极限下确认了三反铁磁相和双反铁磁相的存在。此外,自旋结构因子还揭示了单点平均场分析所遗漏的自旋密度波相的存在。
