We develop a master equation theory for general Bose-Einstein condensates. Starting from first principles, we find that the condensate’s dynamics in the presence of the non-condensed component can be described by a Lindblad master equation, which accounts for all possible two-particle interaction processes. As a first application, we study the process of condensate formation in a 3-dimensional harmonic trap.
