General Idea

We know how to solve single particle problem or the problem of many non-interacting particles--even in external field (ideal gas!). We want to deal with the problem of many interacting particles.

Interactions between particles makes the calculation of partition function (nearly) insolvable
Substitute the forces acting on a given particle by an effective external field
This is mean-field theory. This is a very popular approach in Statistical Physics, Quantum Mechanics (adiabatic approximation), Mechanics, Fluid Mechanics...
