  • While first order phase transitions between incoherence and synchronization are critical for collective behavior in various oscillator system application, e.g., the brain and power grids, such transitions typically require finely tuned properties. In this work the authors show that first order phase transitions and bistability can emerge naturally as a consequence of the presence of higher-order interactions between oscillators.

  • Identifying and mitigating unknown disturbances to complex systems poses a critical challenge in a wide range of disciplines. Here, the authors use machine learning to identify unknown disturbances made to unknown systems and a methodology to suppress these disturbances to recover the undisturbed system.

  • Synchronization bombs are large networks of coupled heterogeneous oscillators that operate in a bistable regime and abruptly transit from incoherence to synchronization by adding one or a few links. Self-organized synchronization bombs would be useful to understand switch mechanisms in biological systems, and to design networks to operate in this regime.
