Four coordination regimes in the (p, T) phase diagram
Where spontaneous coordination dies, where seeded coordination dies, and the frozen pocket between
Fifty-four grid points in the coercion-temperature (p, T) plane, nine coercion values by six temperatures on an L = 64 Ising lattice with absorbing-state dynamics, three seeds each, classified into four regimes: ordered Ising (green circles, the trust regime), disordered (blue squares), frozen order (gold diamonds, only at p = 0.40, T = 0.8 and 1.2) and absorbing DP (red triangles). The dashed curves join boundary crossings read off the grid, with vertical bars showing the grid resolution; the fitted Ising boundary runs from Tc = 2.31 at p = 0 down to 1.25 at p = 0.30 and the fitted DP boundary from 1.22 at p = 0.40 up to 1.55 at p = 1.0. Both are L = 64 features, since finite-size scaling gives pc(∞) = 0.
