Hamiltonian dynamics of a particle interacting with a wave field    [PDF]

Daniel Egli, Jürg Fröhlich, Zhou Gang, Arick Shao, Israel Michael Sigal
We study the Hamiltonian equations of motion of a heavy tracer particle interacting with a dense weakly interacting Bose-Einstein condensate in the classical (mean-field) limit. Solutions describing ballistic subsonic motion of the particle through the condensate are constructed. We establish asymptotic stability of ballistic subsonic motion.
