Cross-Interaction Softness as a Route to Microphase Separation in Binary Colloidal Systems
Umesh Dhumal
Understanding how interparticle interactions govern phase behavior is central to controlling self-organization in multicomponent soft-matter systems. In particular, the role of cro…

Frenkel's entropy-exchange mechanism in monodisperse, nearly hard-sphere colloids: minimal perturbations to access fluid-crystal coexistence
J. Galen Wang, Umesh Dhumal, Monica E. A. Zakhari +1
Entropically driven fluid-solid transitions in monodisperse, purely repulsive hard spheres (MPRHS) are well established in theory, simulation, and experiment for atomic and colloid…

The elusive fluid-and-crystal coexistence state in simulations of monodisperse, hard-sphere colloids
J. Galen Wang, Umesh Dhumal, Monica E. A. Zakhari +1
Monodisperse, purely repulsive, hard spheres (MPRHS) are an important model system for mechanistically exploring phase behavior in atomic systems and colloids. Since the 1940s, pha…
