| We generate 2D Lennard-Jones networks with random topology, by preparing a perfect 4-functional network of identical harmonic springs and randomly cutting some of the springs. Using molecular dynamics simulations we find that the fraction p of active springs affects both the temperature of phase separation and the type of structures observed below this temperature, from network-like high density patterns at p>0.5 ('gel') to droplet-like structures at p<0.5 ('sol'). In the gel domain, these patterns are determined by the interplay between free energy and network topology, with the former dominant as p->1 and the latter as p->0.5. Addon material »»
