Inclusions, Boundaries and Disorder in Scalar Active Matter
Omer Granek, Yariv Kafri, Mehran Kardar +3
Active systems are driven out of equilibrium by exchanging energy and momentum with their environment. This endows them with anomalous mechanical properties that we review in this…
Metastability of Discrete-Symmetry Flocks
Brieuc Benvegnen, Omer Granek, Sunghan Ro +6
We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplet…
Rheology of active fluids
Alfredo Lanzaro, Luigi Gentile
This chapter on the rheology of active fluids is an attempt to correlate theoretical and experimental work. A considerable amount of theoretical work and most of the experimental d…
Metastability of Constant-Density Flocks
Marc Besse, Hugues Chaté, Alexandre Solon
We study numerically the Toner-Tu field theory where the density field is maintained constant, a limit case of "Malthusian" flocks for which the asymptotic scaling of correlation f…
Flocking in One Dimension: Asters and Reversals
Brieuc Benvegnen, Hugues Chaté, Pavel Krapivsky +2
We study the one-dimensional active Ising model in which aligning particles undergo diffusion biased by the signs of their spins. The phase diagram obtained varying the density of…
Fractional Brownian Gyrator
Alessio Squarcini, Alexandre Solon, Pascal Viot +1
When a physical system evolves in a thermal bath at a constant temperature, it arrives eventually to an equilibrium state whose properties are independent of the kinetic parameters…
