Stationary particle currents in sedimenting active matter wetting a wall
Matthieu Mangeat, Shauri Chakraborty, Adam Wysocki +1
Recently it was predicted, on the basis of a lattice gas model, that scalar active matter in a gravitational field would rise against gravity up a confining wall or inside a thin c…
Flocking of two unfriendly species: The two-species Vicsek model
Swarnajit Chatterjee, Matthieu Mangeat, Chul-Ung Woo +2
We consider the two-species Vicsek model (TSVM) consisting of two kinds of self-propelled particles, A and B, that tend to align with particles from the same species and to antiali…
Polar flocks with discretized directions: the active clock model approaching the Vicsek model
Swarnajit Chatterjee, Matthieu Mangeat, Heiko Rieger
We consider the off-lattice two-dimensional -state active clock model (ACM) as a natural discretization of the Vicsek model (VM) describing flocking. The ACM consists of particl…
Effective diffusivity of Brownian particles in a two dimensional square lattice of hard disks
M. Mangeat, T. Guérin, D. S. Dean
We revisit the classic problem of the effective diffusion constant of a Brownian particle in a square lattice of reflecting impenetrable hard disks. This diffusion constant is also…
Narrow escape problem in two-shell spherical domains
Matthieu Mangeat, Heiko Rieger
Intracellular transport in living cells is often spatially inhomogeneous with an accelerated effective diffusion close to the cell membrane and a ballistic motion away from the cen…
Flocking with a -fold discrete symmetry: band-to-lane transition in the active Potts model
Matthieu Mangeat, Swarnajit Chatterjee, Raja Paul +1
We study the -state active Potts model (APM) on a two-dimensional lattice in which self-propelled particles have internal states corresponding to the directions of motio…
