We use a modulated oscillator to study quantum fluctuations far from thermal equilibrium. A simple but important nonequilibrium effect that we discuss first is quantum heating, where quantum fluctuations lead to a finite-width distribution of a resonantly modulated oscillator over its quasienergy (Floquet) states. We also discuss the recent observation of quantum heating. We analyze large rare fluctuations responsible for the tail of the quasienergy distribution and switching between metastable… CONTINUE READING
