Emergent nonreciprocity in open thermodynamically-consistent chemical reaction networks
Daniel Evans, Yizhi Shen, Ahmad K. Omar
Nonreciprocity, a hallmark of nonequilibrium systems, can generate dynamics not possible near thermodynamic equilibrium, including oscillatory and rotating patterns. The onset of t…
Critical Motility-Induced Phase Separation in Three Dimensions is Consistent with Ising Universality
Jiechao Feng, Daniel Evans, Ahmad K. Omar
Identifying the universality class of critical active phase transitions has been the subject of recent interest and controversy. Resolving these controversies will require robust n…
Theory of Nonequilibrium Crystallization and the Phase Diagram of Active Brownian Spheres
Daniel Evans, Ahmad K. Omar
The crystallization of hard spheres at equilibrium is perhaps the most familiar example of an entropically-driven phase transition. In recent years, it has become clear that activi…
Theory of Nonequilibrium Coexistence with Coupled Conserved and Nonconserved Order Parameters
Daniel Evans, Ahmad K. Omar
Phase separation routinely occurs in both living and synthetic systems. These phases are often complex and distinguished by features including crystallinity, nematic order, and a h…
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…
