Medelfältsteori
Medelfältsteori, often translated as mean-field theory, is an approximation method used in physics and other sciences to simplify the study of complex systems with many interacting components. Instead of precisely tracking the interactions of every single particle, medelfältsteori approximates the effect of all other particles on a single particle by an average or "mean" field. This mean field represents the collective influence of the environment on the individual component.
The core idea is to replace the complex, fluctuating interactions with a static, averaged potential. For example,
Medelfältsteori is particularly effective in systems with long-range interactions or a large number of degrees of
