Hexatic Order Coupled with Thermal Noise Produces Bubbles in Two-Dimensional Active Matter
Luke Langford, Ahmad K. Omar
The phase separation of purely-repulsive particles induced by self-propulsion is among the most well-studied non-equilibrium phase transitions. However, some notable features of th…
Multicomponent Linear Transport in the Absence of Local Equilibrium
Yu-Jen Chiu, Eric M. Weiner, Ahmad K. Omar
The linear laws of transport phenomena are central in our description of irreversible processes in systems across the physical sciences. Linear irreversible thermodynamics allows f…
Theory of Nonequilibrium Multicomponent Coexistence
Yu-Jen Chiu, Daniel Evans, Ahmad K. Omar
Multicomponent phase separation is a routine occurrence in both living and synthetic systems. Thermodynamics provides a straightforward path to determine the phase boundaries that…
Phase Separation, Capillarity, and Odd Surface Flows in Chiral Active Matter
Luke Langford, Ahmad K. Omar
Active phase separations evade canonical thermodynamic descriptions and have thus challenged our understanding of coexistence and interfacial phenomena. Considerable progress has b…
