Seminarium KMMF "Teoria Dwoistości"

The Navier-Stokes equations are paradigmatic equations describinghydrodynamics of an interacting system with microscopic interactionsencoded in transport coefficients. An extremely important problem ofnon-equilibrium statistical physics is to show how Navier-Stokesequations arise from microscopic dynamics of particles. In my talk, Iwill present a partial solution to this problem known under the name ofChapman-Enskog theory. In the first part, I will revisit the results forclassical gases governed by the Boltzmann equation. In the second part,I will show how this framework can be generalised to a new class ofsystems, which are weakly perturbed integrable quantum gases.
