报告摘要：In this work, we focus on examining the phase transition to synchronization in four-dimensional (4D) Kuramoto model with isoclinic rotation. We uncover that the synchronization transition is continuous as increasing the strength of coupling. Surprisingly, we find that the uniformly incoherent state loses its stability via a Hopf bifurcation at the critical coupling strength. Subsequently, a time-dependent rhythmic state appears as further increasing the coupling strength，which is found to exist for a pronounced interval of coupling strength. For a sufficiently large coupling strength, the system transits to partially locked states, whereas the rhythmic state no longer exist. We provide the analytic description of the onset of the rhythmic state by performing the linear stability of incoherence. We also obtain a self-consistency equation for the order parameter, which theoretically predicts the degree of coherence of the partially locked sates for the sufficiently large coupling strength.
