Density of states of colloidal glasses

Webimpose barriers of various types between metastable and stable states so that useful colloidal systems can exist for enough time. 10.5.1 A Problem of Semantics Three terms relates to the state of colloid; “stable”, “unstable”, “metastable”. z “metastable” is inconvenient to be used since its meaning can be somewhat ambiguons. WebWe study the phase-ordering dynamics of a 2D model colloidal solid using molecular dynamics simulations. The colloid particles interact with each other with a Hamaker potential modified by the presence of equatorial "patches" of attractive and repulsive regions. The total interaction potential between two such colloids is, therefore, strongly directional and …

WebMar 3, 2024 · By observing as a function of density, we find evidence for a reentrant marginal phase and can begin to map out the phase diagram for colloidal glasses and compare it to the mean field result (6, 14).
