Question:
Analyze the behavior of the atoms’ total energy near the onset of condensation, in the limit of arbitrarily large N (i.e., keeping only the leading order in our 1/N1/3 expansion and approximating the condensation as turning on discontinuously at T = Tc0). More specifically, do the following.
(a) Show that the total energy of the atoms in the magnetic trap is
(b) Show that the specific heat C = (∂Etotal/∂T)N is discontinuous across the critical temperature Tc0:
Note that for gas contained within the walls of a box, there are two specific heats: CV = (∂E/∂T)N,V when the box volume is held fixed, and CP = (∂E/∂T)N,P when the pressure exerted by the box walls is held fixed. For our trapped atoms, there are no physical walls; the quantity held fixed in place of V or P is the trapping potential V(r).
