For a quantum harmonic oscillator coupled to the RWA-oscillator, the authors actually derive Mori's memory kernel equation, which consists of three components, Mori's frequency, Mori's memory function, and Mori's fluctuation. Then the method of expressing the three components in terms of an autocorrelation function of an observable is found. 20 refs.
