Viscosity for a periodic two disk fluid: An existence proof

  • Leonid A. Bunimovich
  • Herbert Spohn
Article

Summary

We express the momentum current (=stress) tensor for a periodic fluid with two hard disks per unit cell in terms of a single particle billiard. We establish a central limit theorem for the time-integrated stress tensor and thereby prove the existence of a strictly positive shear and bulk viscosity.
