• Abstract summary: 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.

• Abstract: Synchronization occurs ubiquitously in nature. 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.

  Synchronization in quantum systems can be induced through applying dissipation on the central sites. Two types of synchronization, stemming from the topological edge states, are characterized by the off-diagonal or diagonal correlations between the boundary sites. Remarkably, the synchronous oscillations maintain steady amplitude and frequency in the thermodynamic limit.
