The TAP-Plefka variational principle for mean field spin glasses

Talk by Dr. David Belius

Date: 23.05.18  Time: 17.15 - 19.00  Room: Y27H12

In this talk I will recall the Thouless-Anderson-Palmer (TAP) approach to the Sherrington-Kirkpatrick model from one of the earliest papers on this model, and describe how it can be reinterpreted as a variational principle in the spirit of the Gibbs variational principle and the Bragg-Williams approximation. Furthermore I will present a rigorous proof of this TAP-Plefka variational principle in the case of the spherical Sherrington-Kirkpatrick model.
