Phase Coexistence Implications of Violating Newton's Third Law
Yu-Jen Chiu, Ahmad K. Omar
Newton's third law, actio = reactio, is a foundational statement of classical mechanics. However, in natural and living systems, this law appears to be routinely violated for const…
Mechanical Theory of Nonequilibrium Coexistence and Motility-Induced Phase Separation
Ahmad K. Omar, Hyeongjoo Row, Stewart A. Mallory +1
Nonequilibrium phase transitions are routinely observed in both natural and synthetic systems. The ubiquity of these transitions highlights the conspicuous absence of a general the…
Topological Forces in a Model System for Reptation Dynamics
Ahmad K. Omar, Yuyuan Lu, Lijia An +1
We construct a micromechanical version of an early model for topologically constrained polymers -- a 2D chain amongst point-like uncrossable obstacles -- which allows us to explici…
Ballistic Ejection of Microdroplets from Overpacked Interfacial Assemblies
Xuefei Wu, Gautam Bordia, Robert Streubel +11
Spontaneous emulsification, resulting from the assembly and accumulation of surfactants at liquid-liquid interfaces, is an interfacial instability where microdroplets are generated…
