The TAP-Plefka variational principle for the spherical SK model
Published 15 Feb 2018 in math.PR, math-ph, and math.MP | (1802.05782v2)
Abstract: We reinterpret the Thouless-Anderson-Palmer approach to mean field spin glass models as a variational principle in the spirit of the Gibbs variational principle and the Bragg-Williams approximation. We prove this TAP-Plefka variational principle rigorously in the case of the spherical Sherrington-Kirkpatrick model.
