Fig. 3: Avalanche size distributions and phase structures in 2D thermal neuristor arrays of different sizes.
From: Collective dynamics and long-range order in thermal neuristor networks
a, b Two different avalanche size distributions at phase boundaries, with both distributions obtained at Cth = 1, but different input voltages (Vin = 9.96 V for (a), and 13.46 V for (b)). c Phase diagram of the thermal neuristor array, with the y-axis depicting the relative value of Cth compared to its experimentally estimated level. We observe synchronized rigid states with collective spiking and quiescent states with no spikes (no activity). Near the phase boundaries, a robust power-law distribution in avalanche sizes is noted across various parameters, signaling the existence of LRO. d Exponents of the power-law fit of the avalanche size distributions (omitting the negative signs for clarity). The phase diagram from (c) is superimposed for enhanced visualization. Regions lacking a colored box signify a failed power-law fit, and exponents are capped at 6 to exclude outliers. Source data are provided in the Source Data file.
