"Charged particle transport in narrow geometries under strong confinement with applications to the simulation of ion channels" |
Kinetic transport in thin tubes, involving scattering of particles with a background, is modeled by classical sub-band type macroscopic equations for the density of particles (ions). The result is a diffusion equation with the projection of the (asymptotically conserved) energy tensor on the confined directions as an additional free variable, on large time scales. Classical transport of ions through protein channels is discussed as an example of the application of this methodology.(Joint work with N. Ben Abdallah and C. Heitzinger) |
