Assuming that the system is in thermal equilibrium with a reservoir at temperature $\\beta^{-1}$, we compute the free energy in the thermodynamic limit $N\\rightarrow\\infty$ in the saddle-point approximation to the path integral and determine the critical temperature for the superradiant phase transition.
