Flocking and reorientation transition in the 4-state active Potts model
Swarnajit Chatterjee, Matthieu Mangeat, Raja Paul +1
We study the active 4-state Potts model (APM) on the square lattice in which active particles have four internal states corresponding to the four directions of motion. A local alig…
The narrow escape problem in a circular domain with radial piecewise constant diffusivity
Matthieu Mangeat, Heiko Rieger
The stochastic motion of particles in living cells is often spatially inhomogeneous with a higher effective diffusivity in a region close to the cell boundary due to active transpo…
The role of non-conservative scattering forces and damping on Brownian particles in optical traps
Matthieu Mangeat, Yacine Amarouchene, Yann Louyer +2
We consider a model of a particle trapped in a harmonic optical trap but with the addition of a non-conservative radiation induced force. This model is known to correctly describe…
Nonequilibrium dynamics induced by scattering forces for optically trapped nanoparticles in strongly inertial regimes
Yacine Amarouchene, Matthieu Mangeat, Benjamin Vidal Montes +4
As a first approximation, the forces acting on optically trapped particles are commonly assumed to be conservative. The influence of the nonconservative force has been shown to be…
Dispersion in two-dimensional periodic channels with discontinuous profiles
M. Mangeat, T. Guérin, D. S. Dean
The effective diffusivity of Brownian tracer particles confined in periodic micro-channels is smaller than the microscopic diffusivity due to entropic trapping. Here, we study diff…
Geometry controlled dispersion in periodic corrugated channels
M. Mangeat, T. Guérin, D. S. Dean
The effective diffusivity of tracer particles diffusing in periodically corrugated axisymmetric two and three dimensional channels is studied. The majority of previous studie…
