Persistence and first-passage properties in nonequilibrium systems
In this review, we discuss the persistence and the related first-passage properties in
extended many-body nonequilibrium systems. Starting with simple systems with one or few …

Intermittent search strategies
This review examines intermittent target search strategies, which combine phases of slow
motion, allowing the searcher to detect the target, and phases of fast motion during which …

Single-molecule tracking in live cells reveals distinct target-search strategies of transcription factors in the nucleus
Gene regulation relies on transcription factors (TFs) exploring the nucleus searching their
targets. So far, most studies have focused on how fast TFs diffuse, underestimating the role …

First-passage times in complex scale-invariant media
How long does it take a random walker to reach a given target point? This quantity, known
as a first-passage time (FPT), has led to a growing number of theoretical investigations over …

From first-passage times of random walks in confinement to geometry-controlled kinetics
We present a general theory which allows one to accurately evaluate the mean first-passage
time (FPT) for regular random walks in bounded domains, and its extensions to related first …

Geometry-controlled kinetics
It has long been appreciated that the transport properties of molecules can control reaction
kinetics. This effect can be characterized by the time it takes a diffusing molecule to reach a …

First passages in bounded domains: When is the mean first passage time meaningful?
We study the first passage statistics to adsorbing boundaries of a Brownian motion in
bounded two-dimensional domains of different shapes and configurations of the adsorbing …
