The dynamical resonance of a harmonic oscillator coupled to a heat bath with harmonic velocity noise and harmonic noise
简谐速度噪声与简谐噪声环境中谐振子的动力学共振

For a harmonic oscillator coupled to a heat bath with harmonic velocity noise and harmonic noise, we obtain the exact average energy by resoving the corresponding generalized quantum Langevin equation. Due to the different power spectra of the two kinds of noise, the harmonic oscillator driven by external harmonic force exhibits different resonant features. This is an approach for examing the characterization of internal noise.
