Quantum synchronization of a driven self-sustained oscillator    [PDF]

Stefan Walter, Andreas Nunnenkamp, Christoph Bruder
Synchronization is a universal phenomenon that is important both in fundamental studies and in technical applications. Here we investigate synchronization in the simplest quantum-mechanical scenario possible, i.e., a quantum-mechanical self-sustained oscillator coupled to an external harmonic drive. Using the power spectrum we analyze synchronization in terms of frequency locking and frequency entrainment in close analogy to the classical case. We show that the quantum system exhibits frequency locking and that the synchronized (frequency-locked) region is reduced due to quantum noise.
