DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IAMP_seminar
 s/191/">Long-time validity of Bogoliubov theory</a>\nby Simone Rademacher 
 (University of Mannheim) as part of One world IAMP mathematical physics se
 minar\n\n\nAbstract\nWe consider the Bogoliubov approximation for the many
 -body quantum dynamics of weakly interacting Bose gases and establish a un
 iform-in-time validity of Bogoliubov theory. The proof relies on a detaile
 d analysis of the dispersive behavior of the symplectic Bogoliubov dynamic
 s\, which allows for a rigorous derivation of the Bogoliubov theory as an 
 effective description of quantum fluctuations around the Bose-Einstein con
 densate on all time scales. This is joint work with Phan Thanh Nam and Avy
  Soffer.\n
