N2 - For a quantum harmonic oscillator coupled to the RWA-oscillator, we actually derive Mori′s memory kernel equation, which consists of three components, Mori′s frequency, Mori′s memory function, and Mori;s fluctuation. Then we find the method of expressing the three components in terms of an autocorrelation function of an observable.
