Zusammenfassung

In numerical calculations of a quantity Λ(T)≡-∂lnχEA′/∂T, where χEA′≡Σ(〈σiσj〉T2)J for finite L×L Edwards-Anderson (EA) models, Fernández [Phys. Rev. B 25, 417 (1982)] finds that Λ(T) has a peak at T0≈0.6 (Gaussian model) or T0≈1.0, for L=4,6,8,10,or 11, respectively. He finds that the peak height Λmax=Λ(T0) increases in direct proportion to L, and interprets his results in terms of a phase ...
