Transport diffusion coefficient for a Knudsen gas in a random tube
Francis Comets, Serguei Popov, Gunter M. Schütz +1
We consider transport diffusion in a stochastic billiard in a random tube which is elongated in the direction of the first coordinate (the tube axis). Inside the random tube, which…

Quenched invariance principle for the Knudsen stochastic billiard in a random tube
Francis Comets, Serguei Popov, Gunter M. Schütz +1
We consider a stochastic billiard in a random tube which stretches to infinity in the direction of the first coordinate. This random tube is stationary and ergodic, and also it is…
