WebAbstract. We define the “BEC state” to be the many-body wavefunction where all particles are in the same one-body state. Using an argument analogous to Anderson’s Orthogonality Catastrophe, we argue that for interacting particles the amplitude of the BEC state within the many-body wavefunction goes to zero in the thermodynamic limit.
