The first passage problem for diffusion through a cylindrical pore with sticky walls — •Nicholas Licata and Stephan Grill — Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

We formulate a simple model to calculate first passage times for diffusion through a cylindrical pore with sticky walls. A particle diffusively explores the interior of the pore through a series of binding and unbinding events with the cylinder wall. Through a diagrammatic expansion we obtain first passage time statistics for the particle's exit from the pore. Connections between the model and nuclear transport are discussed.
