I'm searching for the best physical definition for the "Chemical Potential" as an energy, what I know is that it's a constant set through Lagrange multiplicands which is set to sustain the number of particles. Actually I'm still not convinced with that, it's an energy, and should have some physical meaning.

What I also happen to know is:

1- For free electron theorem chemical potential is Fermi surface, mathematically.

2- In Bosé-Einstein condensation chemical potential for bosons falls to zero when T tends to zero, also mathematically.

3- For photons, phonons, magnons and so have zero chemical potential, because the number of quasi-particles isn't conserved, and so also mathematically!

So guys, any "physics" about this?

Thanks :)
