I notice that some bosons can exhibit Bose-Einstein condensation while others cannot (photons, phonons). Is it true that the bosons can have BEC only when the total number of particles is conserved? In this case, the chemical potential approaches zero at [tex]T_c[/tex], and particles begin to cluster (significantly) in the ground state.
Btw, is the total number of phonons conserved in a system? If it is not, for photons and phonons, [tex]\mu=0[/tex] as particles are not conserved. Thus, no BEC?
What distinguishes between photons and some other bosons such that the total number of particles can be conserved or not?
