Berry Phase for the Two-Spin System with the Uniaxial Anisotropic Exchange Interaction in a Time-Dependent Magnetic Field
【摘要】 讨论了含时磁场下具有单轴各向异性交换作用双自旋系统的瞬时本征态及其绝热周期演化下的Berry相位 ,并由此分析了单轴各向异性交换作用对自旋系统 Berry相位的影响
【Abstract】 The instantaneous eigenstates and Berry phases for the two spin system with the uniaxial exchange interaction in a time dependent magnetic field are studied.The results show that uniaxial anisotropic exchange interaction has the effect to the Berry phase for the spin system. [WT5HZ]
