    "abstract": "It is proven that the energy of a quantum mechanical harmonic oscillator with\na generically time-dependent but cyclic frequency, $\\omega_{0}(t_{0})=\n\\omega_{0}(0)$, cannot decrease on the average if the system is originally in a\nstationary state, after the system goes through a full cycle. The energy\nexchange always takes place in the direction from the macroscopic system\n(environment) to the quantum microscopic system.",
