The van der Pol oscillator has been a favorite model to investigate synchronization. Here we study the oscillator in the deep quantum regime, where nonclassical effects dominate the dynamics. Our results show: (i) squeezed driving loses its effect, (ii) noise boosts synchronization, (iii) synchronization is bounded, and (iv) the limit-cycle is insensitive to strong driving. We propose a synchronization measure and analytically calculate it. These results reflect intrinsic differences between synchronization in the quantum and deep quantum regimes.", "revisions": [ { "version": "v1", "updated": "2020-02-18T11:13:40.000Z" } ], "analyses": { "keywords": [ "deep quantum regime", "van der pol oscillator", "results reflect intrinsic differences", "noise boosts synchronization", "favorite model" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
