Cover times of random searches
M. Chupeau, O. Bénichou, R. Voituriez
How long does it take a random searcher to visit all sites of a given domain? This time, known as the cover time, is a key observable to quantify the efficiency of exhaustive searc…
Universality classes of foraging with resource renewal
M. Chupeau, O. Bénichou, S. Redner
We determine the impact of resource renewal on the lifetime of a forager that depletes its environment and starves if it wanders too long without eating. In the framework of the mi…
Mean perimeter of the convex hull of a random walk in a semi-infinite medium
M. Chupeau, O. Bénichou, S. N. Majumdar
We study various properties of the convex hull of a planar Brownian motion, defined as the minimum convex polygon enclosing the trajectory, in the presence of an infinite reflectin…
Optimal strategy to capture a skittish lamb wandering near a precipice
M. Chupeau, O. Bénichou, S. Redner
We study the splitting probabilities for a one-dimensional Brownian motion in a cage whose two boundaries move at constant speeds and . This configuration corresponds to…
Survival probability of a Brownian motion in a planar wedge of arbitrary angle
Marie Chupeau, Olivier Bénichou, Satya N. Majumdar
We study the survival probability and the first-passage time distribution for a Brownian motion in a planar wedge with infinite absorbing edges. We generalize existing results obta…
