WebApr 8, 2024 · In this work we show that for Sherrington-Kirkpatrick (i.e. 2-spin) interactions, it can also be expressed in terms of a Thouless-Andersson-Palmer (TAP) variational principle. This is only the second spin glass model where a mathematically rigorous TAP computation of the free energy at all temperatures and external fields has been achieved.

WebS-K Spin Glass Model 5 (i.e. the "quenched" and the "annealed" free energies agree) - which is predicted by Sherrington and Kirkpatrick [1] and Thouless et al. [3] to hold for βj < 1. In such case, the sharpness of the distribution of the free energy density may be deduced from just the mean value. WebSep 18, 2012 · The Sherrington-Kirkpatrick Model In 1975, Sherrington and Kirkpatrick [ 37] introduced a mean field model for a spin glass—a disordered magnetic alloy that exhibits unusual magnetic behavior. Given a configuration of N Ising spins, \sigma= (\sigma_1,\ldots,\sigma_N) \in \varSigma_N = \ {-1,+1\}^N, the Hamiltonian of the model … certified application assistor training
