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…
The Mechanics of Nucleation and Growth and the Surface Tensions of Active Matter
Luke Langford, Ahmad K. Omar
Homogeneous nucleation, a textbook transition path for phase transitions, is typically understood on thermodynamic grounds through the prism of classical nucleation theory. However…
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…
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…
