The mean-field approximation

http://proceedings.mlr.press/v75/jain18b/jain18b.pdf Splet19. mar. 2024 · By duality, these transportation-entropy inequalities imply a strong integrability inequality for Bernoulli and exponential processes. As a result, we obtain a dimension-free mean-field approximation of the free energy of a Gibbs measure and a dimension-free nonlinear large deviations bound on the discrete hypercube.

Splet21. jan. 2024 · The idea to keep in mind is that the mean-field treatment works. Up to now, we nevertheless restrict ourself to operator formalism. When dealing with quantum field theory and its methods, one would prefer to use the Wick's theorem. So, now we come back to the Wick's decomposition. One can manipulate the statistical average and show that SpletSo let me emphasize that the mean-field approximation is not exact in the thermodynamic limit. It is usually accurate at high temperatures. It is rarely accurate near phase transitions.
