Finite-size scaling and double-crossover critical behavior in two-dimensional incompressible polar active fluids
Wanming Qi, Lei-Han Tang, Hugues Chaté
We study the order-disorder transition in two-dimensional incompressible systems of motile particles with alignment interactions through extensive numerical simulations of the inco…
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…
Susceptibility of Polar Flocks to Spatial Anisotropy
Alexandre Solon, Hugues Chaté, John Toner +1
We consider the effect of spatial anisotropy on polar flocks by investigating active -state clock models in two dimensions. In contrast to what happens in equilibrium, we find t…
Small Obstacle in a Large Polar Flock
Joan Codina, Benoît Mahault, Hugues Chaté +3
We show that arbitrarily large polar flocks are susceptible to the presence of a single small obstacle. In a wide region of parameter space, the obstacle triggers counter-propagati…
Susceptibility of Orientationally-Ordered Active Matter to Chirality Disorder
Bruno Ventejou, Hugues Chaté, Raul Montagne +1
We investigate the susceptibility of long-range ordered phases of two-dimensional dry aligning active matter to population disorder, taken in the form of a distribution of intrinsi…
