Hamiltonian dynamics of a particle interacting with a wave field [PDF]
Daniel Egli, Jürg Fröhlich, Zhou Gang, Arick Shao, Israel Michael SigalWe 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.View original: http://arxiv.org/abs/1211.6154
