Geometric Phase of the 3-particle Spin Chain
Song Yuan-jun, Shun-Jin Wang · Journal of Sichuan University · 2005
Using algebraic dynamics, the geometric phase of a 3-particle spin chain has been calculated. The dependence of the geometric phase of this system on the symmetry of Hamiltonian is investigated. It is found that when the symmetry of Hamiltonian is broken, a drastic change in the structure of the geometric phase takes place.
