Hudson Group: Emerging Coherence

Emerging Coherence

Incoherent state of the population of 64 electrochemical periodic oscillators without interactions. Each circle represents an oscillator in the phase space and its color denotes the frequency of the oscillator with red for the fastest and blue for the slowest. watch movie

Synchronized state of the population of 64 electrochemical periodic oscillators with weak interactions. All oscillators have the same frequency and move together as a whole entity along the limit circle in the phase space. watch movie
