KnowraMean-field theoryLinked fromLinked fromThe 19 pages that link to Mean-field theory, each with the reason it gives.All 19Broader topic 1Related 6Narrower topic 2Compared with 10Universality classCompared with: It often predicts exponents that differ from the true class below the upper critical dimension.Critical phenomenaCompared with: It predicts simple critical exponents but often misses fluctuations in low dimensions.Lattice modelCompared with: It suppresses spatial correlations that explicit lattice models can retain.Cavity methodCompared with: Mean-field theory neglects detailed local neighborhoods that cavity methods retain.1-dimensional systems (physics)Compared with: Its neglect of strong fluctuations often makes it unreliable for one-dimensional systems.Classical spin modelsCompared with: It simplifies spin models but neglects many spatial correlations and fluctuations.Collective behavior in networksCompared with: It suppresses specific network connections that can determine collective outcomes.Collective effects in atomic physicsCompared with: It captures some shared-field behavior but can miss correlations between individual atoms.Disordered systemsCompared with: Averaging can miss spatial fluctuations and rare regions central to disordered systems.Many-body techniquesCompared with: It is simpler than methods retaining fluctuations and correlations beyond the average field.
