Question

What is the wavefunction of a Bose-Einstein condensate made of composite particles?

Answer 1

all particles thatbose condense are composite particles,made out of fermions, so they should have a completely antisymmetric wavefunction.

Answer 2

But in reality, all particles that bose condense are composite particles, made out of fermions, so they should have a completely antisymmetric wavefunction. For example, we could say each boson is made out of a pair of fermions, and R i = r i 1 + r i 2 2 is really the center of mass of the two fermions.
