Universal bifurcations to explosive synchronization for networks of coupled oscillators with higher-order interactions

Abstract: We determine critical parameter sets for transitions from gradual to explosive synchronization in coupled oscillator networks with higher-order coupling using self-consistency analysis. We obtain analytic bifurcation values for generic symmetric natural frequency distributions. We show that non-synchronized, drifting, oscillators are non-negligible, and play a crucial role in bifurcation. As such, the entire natural frequency distribution must be accounted for, rather than just the shape at the center. We verify our results for Lorentzian and Gaussian distributed natural frequencies.
