Due to the interaction the particle will experience dissipa tion and fluctuation. Both effects will typically increase as the density goes to infinity.\n\nWhile this is true for a classical gas and also for B ose gases\, the behaviour is very different for gases of Fermions: A charg ed particle moving through a Fermi sea of high density behaves almost like a free particle.\n\nHere the Fermi pressure leads to a suppression of the fluctuations in the gas and eventually a suppression of fluctuation and d issipation.\n\nWhile this is easy to prove in one dimension\, the two dime nsional case is highly non trivial. I will present recent results on this question.\n LOCATION:https://researchseminars.org/talk/OSAnaProb/6/ END:VEVENT END:VCALENDAR
