29. The technical details of the standard field-theoretic methods leading to the following expression for the free energy functional, derived from the lagrangian in Eq. (1), may be found for example in chapter 17 of Ref. [14] (in particular, for the derivation of the expressions for the critical temperature, see the section of this chapter devoted to the finite temperature field theory for the Higgs mechanism).
30. In this section, in order to facilitate possible comparison of the theoretical predictions with the experimental data, we shall use conventional units and hence restore the constants ℏ, c, k.
