Figure 4. Phase space domains and Poincaré section of two-species BJJ, with uab = −0.1622. Black and red represent the two-species a and b. (a) phase space domains under constant coupling; (b) phase space domains under occasional coupling, here T = 0.3, θ = 0.5; (c) Poincaré sections under constant coupling; (d) Poincaré sections under occasional coupling, here T = 0.3, θ = 0.5.
