研究了在非含时磁场作用下两自旋相互作用系统的纠缠度与几何相位的关系。一般的纠缠依赖的几何相位制定。这个统一方案涵盖了Sjoeqvist对旋进自旋和各向同性相互作用自旋的分析。从一般公式，几何相位明确确定各向同性相互作用和非零磁场。
The entanglement dependence of the geometric phase is studied in the case of two interacting spins under a time-independent magnetic field. A general entanglement-dependence geometric phase is formulated. This unification scheme covers the analyses by Sjoeqvist for precessing spins and for isotropically interacting spins. From the general formula, the geometric phase is determined explicitly for an isotropic interaction and nonzero magnetic field.
