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…
Survival probability of stochastic processes beyond persistence exponents
N. Levernier, M. Dolgushev, O. Bénichou +2
For many stochastic processes, the probability of not-having reached a target in unbounded space up to time follows a slow algebraic decay at long times, $S(t)\sim S_0/t…
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…
Mean first-passage times of non-Markovian random walkers in confinement
T. Guérin, N. Levernier, O. Bénichou +1
The first-passage time (FPT), defined as the time a random walker takes to reach a target point in a confining domain, is a key quantity in the theory of stochastic processes. Its…
