Self-Oscillators in the Quantum Regime

Niels Lörch

Self-oscillators are dissipatively driven systems that exhibit self-sustained limit cycle oscillations. The state of a quantum self-oscillator can posses nonclassical characteristics such as boson antibunching and negative Wigner quasi-probability density. When coupling quantum self-oscillators to each other or to an external drive, their synchronization behavior can drastically differ from classical expectations. For example synchronization of identical oscillators can be suppressed in the deep quantum regime. We present analytical results to discuss what system parameters are required to demonstrate these quantum effects in systems such as trapped ions, optomechanical systems and superconducting circuits.
