Abstract
In this chapter, we discuss a formulation of mean-field (MF) theory which puts the derivation in the previous chapter on a somewhat firmer footing and which often proves to be more convenient. It is based on the observation that the result of MF theory, as developed in the previous chapter, was the construction of an effective Hamiltonian which replaced interactions between particles by an effective field which was self-consistently determined.
