摘要
用Robertson理论推导一个在纵磁场和横周期场作用下的自旋的运动方程。得到了阻尼和自旋稳定态对外场强度、频率及与热库的耦合系数的依赖关系。讨论了自旋稳定态的结构及其形成原因。
Robertson's theory is applied to derive the master equations of a spin under the action of a static longitudinal field and a rotating transverse field. The damping and the steady state of the spin are obtained as functions of field strength, frequency and the coupling with the bath The structure of the steady state and its origin are discussed.
