Arrested phase separation in a short-ranged attractive colloidal system: A numerical study

摘要: We numerically investigate the competition between phase separation and dynamical arrest in a colloidal system interacting via short-ranged attractive potential. Equilibrium fluid configurations are quenched at two different temperatures below critical temperature followed during their time evolution. At lowest studied T, phase-separation process is interrupted by formation of an glass dense phase. higher no observed proceeds endlessly simulated window. The final structure retains memory form frozen spinodal decomposition peak, whose location amplitude controlled average packing fraction. also discuss evolution nonergodicity parameter, providing evidence progressively decreasing localization length on increasing Finally, we confirm that reported results independent microscopic dynamics.
