Convex hull of a Brownian motion in confinement
M. Chupeau, O. Bénichou, S. N. Majumdar
We study the effect of confinement on the mean perimeter of the convex hull of a planar Brownian motion, defined as the minimum convex polygon enclosing the trajectory. We use a mi…
Microscopic theory for negative differential mobility in crowded environments
O. Bénichou, P. Illien, G. Oshanin +2
We study the behavior of the stationary velocity of a driven particle in an environment of mobile hard-core obstacles. Based on a lattice gas model, we demonstrate analytically tha…
Exit time distribution in spherically symmetric two-dimensional domains
J. -F. Rupprecht, O. Bénichou, D. S. Grebenkov +1
The distribution of exit times is computed for a Brownian particle in spherically symmetric two- dimensional domains (disks, angular sectors, annuli) and in rectangles that contain…
Mean cover time of one-dimensional persistent random walks
Marie Chupeau, Olivier Bénichou, Raphaël Voituriez
The cover time is defined as the time needed for a random walker to visit every site of a confined domain. Here, we focus on persistent random walks, which provide a minimal model…
Mean exit time for surface-mediated diffusion: spectral analysis and asymptotic behavior
O. Bénichou, D. S. Grebenkov, L. Hillairet +3
We consider a model of surface-mediated diffusion with alternating phases of pure bulk and surface diffusion. For this process, we compute the mean exit time from a disk through a…
Generalized Langevin equations for a driven tracer in dense soft colloids: construction and applications
Vincent Démery, Hugo Jacquin, Olivier Bénichou
We describe a tracer in a bath of soft Brownian colloids by a particle coupled to the density field of the other bath particles. From the Dean equation, we derive an exact equation…
