Theory of Capillary Tension and Interfacial Dynamics of Motility-Induced Phases
Luke Langford, Ahmad K. Omar
The statistical mechanics of equilibrium interfaces has been well-established for over a half century. In the last decade, a wealth of observations have made increasingly clear tha…
Phase Diagram of Active Brownian Spheres: Crystallization and the Metastability of Motility-Induced Phase Separation
Ahmad K. Omar, Katherine Klymko, Trevor GrandPre +1
Motility-induced phase separation (MIPS), the phenomenon in which purely repulsive active particles undergo a liquid-gas phase separation, is among the simplest and most widely stu…
Microscopic Origins of the Swim Pressure and the Anomalous Surface Tension of Active Matter
Ahmad K. Omar, Zhen-Gang Wang, John F. Brady
The unique pressure exerted by active particles -- the "swim" pressure -- has proven to be a useful quantity in explaining many of the seemingly confounding behaviors of active par…
Swimming to Stability: Structural and Dynamical Control via Active Doping
Ahmad K. Omar, Yanze Wu, Zhen-Gang Wang +1
External fields can decidedly alter the free energy landscape of soft materials and can be exploited as a powerful tool for the assembly of targeted nanostructures and colloidal ma…
