Abstract
Recent studies of active matter have stimulated interest in the driven self-assembly of complex structures. Phenomenological modeling of particular examples has yielded insight, but general thermodynamic principles unifying the rich diversity of behaviors observed have been elusive. Here, we study the stochastic search of a toy chemical space by a collection of reacting Brownian particles subject to periodic forcing. We observe the emergence of an adaptive resonance in the system matched to the drive frequency, and show that the increased work absorption by these resonant structures is key to their stabilization. Our findings are consistent with a recently proposed thermodynamic mechanism for far-from-equilibrium self-organization.
Highlights
Matter is termed “active” when it experiences sustained inputs of work energy from chemical, mechanical, or other sources at the single-particle level
Even active matter systems of quite simple composition can exhibit a striking array of complex collective behaviors, some of which mimic dynamical patterns found in living organisms [1,2,3,4,5]
While it is known that being driven far from equilibrium is essential to many phenomena that emerge in active matter, it is challenging to make general thermodynamic statements that constrain or explain experimental observations
Summary
Matter is termed “active” when it experiences sustained inputs of work energy from chemical, mechanical, or other sources at the single-particle level.
