Catching Quantum Rhythm: Synchronization in a Driven Oscillator
![The steady-state synchronization of a van der Pol oscillator, quantified by [latex]\delta[/latex], exhibits a complex relationship with damping and driving strength; strong phase-locking and collective dynamics ([latex]\delta >> 1[/latex]) emerge within specific parameter regimes, while weak or absent phase-locking ([latex]\delta > 1[/latex]) dominates outside these “tongues,” a behavior mirrored across classical and quantum systems-where increased driving force qualitatively enhances nonclassicality up to the quantum limit ([latex]\kappa_{2} = 1[/latex])-and ultimately converges towards synchronization patterns reminiscent of the classical case even in the deep quantum regime ([latex]\kappa_{2} >> 1[/latex]).](https://arxiv.org/html/2512.21272v1/Fig1c.jpg)
