摘要利用旋转坐标系方法求得自旋 1粒子在旋转磁场下的精确解 ,用所求出的精确解计算出自旋极化矢量、三能级的Rabi振荡、非绝热动力学相和几何相等重要物理量的解析形式及数值解 .所得结果对讨论量子光学和量子计算的某些问题有一定意义 . In this paper we obtained the exact solution of spin-1 particles under rotating magnetic field with the rotating frame method.The accurate analytic expressions of some important physical quantities,such as the polarization vector,three energies Rabi oscillation,non-adiabatic dynamic and geometric phases are obtained.The numerical results for above physical quantities are reasonable.The exact solution is useful for discussing some problems in quantum optics and quantum computation.
