Gross-Pitaevskii equation for the dynamics of the Bose condensate
- Laszlo Erdös (LMU, München, Germany)
The time dependent Gross-Pitaevskii equation describes the dynamics of initially trapped Bose-Einstein condensates. We present a rigorous proof of this fact starting from a many-body bosonic Schroedinger equation with a short scale repulsive interaction in the dilute limit. Our proof shows the persistence of an explicit short scale correlation structure in the condensate. This is a joint work with B. Schlein and H.T. Yau.
