We study the effective dynamics of heavy, quantum-mechanical particles (tracer particles) that interact with a Bose-Einstein condensate — we assume that the tracer particle’s mass, and the size of the condensate is of the same order of magnitude, N. For large N, the dynamics of the microscopic system is expected to be described by a pair of (interacting) macroscopic variables: the classical positions of the tracer particles, and the condensate’s wave function. In this talk, we present new quantitative results concerning the validity of this approximation.
