Cluster dynamics of relaxation oscillators on extended triangle and NLR networks.

<p>Left panels: current vs time of the electrodes. Right panels: coupling topology and schematic of synchronization patterns. a: (3–3) two-cluster state in which the synchronized center (2–4) oscillators (black) are in anti-phase configuration to the periphery (1,5,6) oscillators (red). <i>V</i>=1290 mV, <i>R</i>_ind= 1200 Ω, <i>R</i>= 1500 Ω. b: (2,4) two-cluster states in anti-phase synchronization. <i>V</i>=1300 mV, <i>R</i>_ind=1200 Ω, <i>R</i>= 1000 Ω. c: (10–10) condensed two-cluster cluster state with the NLR network. Oscillators in one half of the circle (red) are anti-phase synchronized with oscillators in the other half (black). <i>V</i>=1335 mV, <i>R</i>_ind=1200 Ω, <i>R</i>=5000 Ω. d: (10–10) two-cluster condensed state with combined resistive-capacitive coupling. <i>V</i>=1190 mV, <i>R</i>_ind= 1000 Ω, <i>C</i>=33 μΦ. e: (10–10) flip-flop two-cluster synchronized state in which the red elements are anti-phase synchronized with black elements. <i>V</i>=1190 mV, <i>R</i>_ind= 1000 Ω, <i>C</i>=33 μΦ.
