Fastest first-passage time for multiple searchers with finite speed
Denis S. Grebenkov, Ralf Metzler, Gleb Oshanin
We study analytically and numerically the mean fastest first-passage time (fFPT) to an immobile target for an ensemble of independent finite-speed random searchers driven by di…
Transport collapse in dynamically evolving networks
Geoffroy Berthelot, Liubov Tupikina, Min-Yeong Kang +2
Transport in complex networks can describe a variety of natural and human-engineered processes including biological, societal and technological ones. However, how the properties of…
Diffusion-controlled reactions with non-Markovian binding/unbinding kinetics
Denis S. Grebenkov
We develop a theory of reversible diffusion-controlled reactions with generalized binding/unbinding kinetics. In this framework, a diffusing particle can bind to the reactive subst…
Escape of a Sticky Particle
Yuval Scher, Shlomi Reuveni, Denis S. Grebenkov
Adsorption to a surface, reversible-binding, and trapping are all prevalent scenarios where particles exhibit "stickiness". Escape and first-passage times are known to be drastical…
Slip length for a viscous flow over spiky surfaces
Alexei T. Skvortsov, Denis S. Grebenkov, Leon Chan +1
For a model of a 3D coating composed of a bi-periodic system of parallel riblets with gaps we analytically derive an approximate formula for the effective slip length (an offset fr…
An encounter-based approach to the escape problem
Denis S. Grebenkov
We revise the encounter-based approach to imperfect diffusion-controlled reactions, which employs the statistics of encounters between a diffusing particle and the reactive region…
