摘 要: | By using the normal-ordering technique in the coherent state representation,we discuss the dynamical evolution of the coherence of a Schrodinger cat state in a high Q cavity coupled to another resonator in the presence of external fields.During the progression of the coherence,we pay particular attention to the effect of the external fields,as well as to the initial phase of the Schrodinger cat state.
