[Soft-matter] Soft Matter & Complex Systems Seminar on 24 May 2024

[Piotr Szymczak]

Dear Soft Matter & Complex Systems Colleagues and Friends,

On Friday 24 April 2024 at 9:30 AM at the UW Faculty of Physics 
(Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which

Maciej Łebek (IFT UW)

will give a talk

Navier-Stokes equations for nearly integrable quantum gases

Abstract

Hydrodynamics is an effective theory which describes non-equilibrium 
dynamics at large scales of space and time. The famous Navier-Stokes 
equations have a universal form and the microscopic details of the model 
enter only through transport coefficients, which are non-trivial to 
calculate. In my talk, I will recall classic results from kinetic theory 
regarding derivation of Navier-Stokes equations and calculation of 
transport coefficients for weakly interacting classical gas. Then, I 
will show that these methods can be generalized to the case of nearly 
integrable quantum gases, which are strongly correlated. Our solution 
builds on the exactly known thermodynamics and hydrodynamics of 
integrable systems and can be understood as a perturbation theory around 
interacting, integrable theories.



We warmly welcome everyone to attend the talk and the Soft Matter Coffee 
Break after the seminar, held in room 2.63 (2nd floor).
