Genuine Quantum Signatures in Synchronization of Anharmonic Self-Oscillators — Niels Loerch1, •Ehud Amitai1, Andreas Nunnenkamp2, and Christoph Bruder1 — 1Department of Physics, University of Basel, Basel, Switzerland — 2Cavendish Laboratory, University of Cambridge, Cambridge, United Kingdom
We study the synchronization of a Van der Pol self-oscillator with Kerr anharmonicity to an external drive. We demonstrate that the anharmonic, discrete energy spectrum of the quantum oscillator leads to multiple resonances in both phase locking and frequency entrainment not present in the corresponding classical system. Strong driving close to these resonances leads to nonclassical steady-state Wigner distributions. Experimental realizations of these genuine quantum signatures can be implemented with trapped ions or optomechanical systems.
