Higher order corrections to the mean-field dynamics of interacting bosons

Date: Thursday, November 21, 2019 16:00 - 18:00
Speaker: Lea Bossmann (IST Austria)
Location: Heinzel Seminar Room / Office Bldg West (I21.EG.101)
Series: Mathematics and CS Seminar
Host: Robert Seiringer

We consider the dynamics of N bosons which are initially in a Bose-Einstein condensate and interact via pair interactions in the mean-field scaling regime. We derive a sequence of N-body functions which approximate the true many-body dynamics in norm to arbitrary precision in powers of 1/N. Joint work with Natasa Pavlovic, Peter Pickl, and Avy Soffer.
