Figure 1 Schematic showing twocolor formationof molecules in their ground electronic state by RamanPhotoassociation In a BEC this process is initially coherent andleads to a wavefunction that is both atoms and moleculesWhena system enters the BEC phase a sizable fraction of the totalnumber of particles enters the ground state until at some pointalmost all of your particles are in the ground stateIn reality you almost always find that the particles prefer togo to the same state because of some tiny energy shifts in thesystem For example a ferromagnetic condensate can have manydegenerate states but there is an energy cost for particles thatdisagree These systems will break symmetry by having all theparticles choose the same arbitrary stateOne exception is if the number of degenerate states is largefor instance larger than the number of particles I have heard thatclaim that if the system has a sufficiently large degeneracy forinstance if all momentum states has the same energy See Answer
