dr Leonardo Tinti (UJK): Regularized hydrodynamic expansion from quantum field

Friday Nov 26, 2021, 10:15 AM → 11:00 AM Europe/Warsaw

Abstract:

Relativistic hydrodynamics is surprisingly predictive, even in the presence of large gradients and deviations from equilibrium. The method of moments can be used in a relativistic gas to justify such behavior, but it can’t be applied in the quantum case,  since some crucial quantities become ill-defined. It is possible however to modify the method in terms of regularized moments that are well defined even for the quantum precursor of the distribution function. Recovering in that way the hydrodynamic expansion and maintain the fast convergence to the exact solutions in the exactly solvable case.

 

Important: This seminar is held in building D-11 room 104. 

Please, be advised that due to the pandemic sanitary rules, we can absorbe 1 unvaccinated person per 10m^2, which means 4 people. As most of us are vaccinated, this should not be a problem. There will be a list of participants, stating that they were (or were not) vaccinated / are immune / with a valid covid test, where we will ask you to sign in upon arrival. Also, people with ANY symptoms of cold (either of running nose, cough, temperature, ...), not necessarily covid, are not allowed to participate according to the rules. We hope you understand. The situation is dynamic and we will of course keep you posted. At the moment we plan to proceed “live”, similary to teaching at AGH.
