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…
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…
Thermodynamically consistent flocking: From discontinuous to continuous transitions
Tal Agranov, Robert L. Jack, Michael E. Cates +1
We introduce a family of lattice-gas models of flocking, whose thermodynamically consistent dynamics admits a proper equilibrium limit at vanishing self-propulsion. These models ar…
