摘要
Abstract
The coordinate rotation method is applied to investigate the relation between two types of gauge analytical solutions for a su(2) algebraically symmetric spin cluster. We consider an annular 3-
spin y chain with partially anisotropic coupling. It is found that the analytical solutions related to single-gauge transformation can be obtained from those related to double-gauge transformation. The geometric phase of the every basic analytical solution from single-gauge transformation is calculated, and
the geometric phase π is found. If A = π/2 in double-gauge transformation, the value of geometric phase
obtained here is the same as that of every basic analytical solution from double-gauge transformation.关键词
