Universality and ambiguity in extremes of anomalous diffusion
Sean D Lawley
Many biophysical processes begin when the fastest searcher finds a target out of many random searchers, which is called an extreme or fastest first passage time (fFPT). In some mod…
Channel transport: gating, geometry, and heterogeneous diffusion
Sean D Lawley
Channel-mediated transport is ubiquitous in biology. A series of works by different theoreticians have sought to determine how the diffusive flux through a channel depends on (a) s…
Diffusive flux into a stochastically gated tube
Sean D Lawley
Diffusion-influenced reactions in the presence of gates which randomly open and close have been studied for decades in a variety of biophysical and biochemical scenarios. The diffu…
Yet another look at narrow escape through a tube
Victorya Richardson, Yick Hin Ling, Sean D Lawley
The narrow escape problem concerns the time needed for a diffusing particle to exit a confining domain through a small hole in the boundary. While this problem is now well-understo…
Stochastic search with space-dependent diffusivity
Hwai-Ray Tung, Sean D Lawley
The canonical model of stochastic search tracks a randomly diffusing "searcher" until it finds a "target." Owing to its many applications across science and engineering, this peren…
Escape from heterogeneous diffusion
Hwai-Ray Tung, Sean D Lawley
Many physical processes depend on the time it takes a diffusing particle to find a target. Though this classical quantity is now well-understood in various scenarios, little is kno…
