Field of reference: Physics

Description:  Multi-particle physical systems are so complex that only a very efficient approximate treatment is possible. The mean free theory describes such physical systems as individual particles evolving under the influence of an effective force, which is the combined force exerted by the rest of the system.

"Mean field theory (MFT, also known as self-consistent field theory) is a method to analyse physical systems with multiple bodies. A many-body system with interactions is generally very difficult to solve exactly, except for extremely simple cases (random field theory, 1D Ising model). The n-body system is replaced by a 1-body problem with a chosen good external field. The external field replaces the interaction of all the other particles to an arbitrary particle."
