Coupling strength (k) dependence of the phase fluctuation in the two-node network studied in Fig. 1a. (a) Peak-to-peak fluctuation magnitudes Δ1,2 under different coupling strength k when f = 0.5Hz, α = 0.1, A = 0.2. (b) Peak-to-peak fluctuation magnitudes Δ1,2 under different coupling strength k when f = 1Hz, α = 0.1, A = 0.2. (c) Dependence of the “optimal” coupling strength on the driving forcing frequency f with A = 0.2 and various values of α. (d) Dependence of the “optimal” coupling strength on the driving forcing frequency f with α = 0.1 and various values of A.
