Irreversibility in scalar active turbulence: The role of topological defects
Byjesh N. Radhakrishnan, Francesco Serafin, Thomas L. Schmidt +1
In many active systems, swimmers collectively stir the surrounding fluid to stabilize some self-sustained vortices. The resulting nonequilibrium state is often referred to as activ…
Entropy production rate in thermodynamically consistent flocks
Tal Agranov, Robert L. Jack, Michael E. Cates +1
We study the entropy production rate (EPR) of aligning self-propelled particles which undergo a flocking transition towards a polarized collective motion. In our thermodynamically…
Species interconversion of deformable particles yields transient phase separation
Yiwei Zhang, Alessandro Manacorda, Ãtienne Fodor
We consider a dense assembly of repulsive particles whose fluctuating sizes are subject to an energetic landscape that defines three species: two distinct states of particles with…
Biased ensembles of pulsating active matter
William D. Piñeros, Ãtienne Fodor
We discover unexpected connections between packing configurations and rare fluctuations in dense systems of active particles subject to pulsation of size. Using large deviation the…
Diffusive oscillators capture the pulsating states of deformable particles
Alessandro Manacorda, Ãtienne Fodor
We study a model of diffusive oscillators whose internal states are subject to a periodic drive. These models are inspired by the dynamics of deformable particles with pulsating si…
Nonequilibrium Thermodynamics of Non-Ideal Reaction-Diffusion Systems: Implications for Active Self-Organization
Francesco Avanzini, Timur Aslyamov, Ãtienne Fodor +1
We develop a framework describing the dynamics and thermodynamics of open non-ideal reaction-diffusion systems, which embodies Flory-Huggins theories of mixtures and chemical react…
