Active Matter
The term active matter describes diverse systems, spanning macroscopic (e.g. shoals of fish and flocks of birds) to microscopic scales (e.g. migrating cells, motile bacteria and gels formed through the interaction of nanoscale molecular motors with cytoskeletal filaments within cells). Such systems are often idealizable in terms of collections of individual units, referred to as active particle...

متن کاملDynamical freezing of active matter.
W hen collections of interacting particles are externally driven, they typically form strongly fluctuating states with short-lived structures or patterns that are continually created and destroyed, such as those found in turbulent fluids (1) or fluctuating granular matter (2). In some cases, however, such driven systems do not remain in a strongly fluctuating state but instead organize into a p...
متن کاملStochastic thermodynamics for active matter
The theoretical understanding of active matter, which is driven out of equilibrium by directed motion, is still fragmental and model oriented. Stochastic thermodynamics, on the other hand, is a comprehensive theoretical framework for driven systems that allows to define fluctuating work and heat. We apply these definitions to active matter, assuming that dissipation can be modelled by effective...
متن کاملCritical phenomena in active matter.
We investigate the effect of self-propulsion on a mean-field order-disorder transition. Starting from a φ^{4} scalar field theory subject to an exponentially correlated noise, we exploit the unified colored-noise approximation to map the nonequilibrium active dynamics onto an effective equilibrium one. This allows us to follow the evolution of the second-order critical point as a function of th...
