| Title: | The marginal stability of the metastable TAP states |
| Language: | English |
| Abstract: | The existing investigations on the complexity are extended. In addition to the Edward–Anderson parameter q₂ the fourth moment q₄ = 1/NΣᵢmᵢ⁴ of the magnetizations mi is included to the set of constrained variables and the constrained complexity Σ(T; q₂, q₄) is numerical determined. The maximum of Σ(T; q₂, q₄) (representing the total complexity) sticks at the boundary for temperatures at and below a new critical temperature. This implies marginal stability for the nearly all metastable states. The temperature dependence of the lowest value of the Gibbs potential consistent with various physical requirements is presented. |
