We analyze the Thouless-Anderson-Palmer (TAP) approach to the spherical p-spin spin glass model in zero external field. The TAP free energy is derived by summing up all the relevant diagrams for N → ∞ of a diagrammatic expansion of the free energy. We find that if the multiplicity of the TAP solutions is taken into account, there is a first order transition in the order parameter at the critical temperature T c higher than that predicted by the replica solution T RSB , but in agreement with the… 

Dynamical TAP approach to mean field glassy systems

The Thouless, Anderson and Palmer (TAP) approach to thermodynamics of mean field spin glasses is generalized to dynamics. A method to compute the dynamical TAP equations is developed and applied to

Spin-glass theory for pedestrians

In these notes the main theoretical concepts and techniques in the field of mean-field spin glasses are reviewed in a compact and pedagogical way, for the benefit of the graduate and undergraduate

Quenched complexity of the mean-field p-spin spherical model with external magnetic field

We consider the p-spin spherical spin-glass model in the presence of an external magnetic field as a general example of a mean-field system where a one-step replica symmetry breaking (1-RSB) occurs.

Large time zero temperature dynamics of the spherical p  =  2-spin glass model of finite size

We revisit the long time dynamics of the spherical fully connected p  =  2-spin glass model, when the number of spins N is large but finite. At T  =  0 where the system is in a (trivial) spin-glass

An investigation of the hidden structure of states in a mean-field spin-glass model

We study the geometrical structure of the states in the low-temperature phase of a mean-field model for generalized spin glasses, the p-spin spherical model. This structure cannot be revealed by the

High temperature TAP upper bound for the free energy of mean field spin glasses

Abstract. This work proves an upper bound for the free energy of the SherringtonKirkpatrick model and its generalizations in terms of the Thouless-Anderson-Palmer (TAP) energy. The result applies to

Spherical 2+p spin-glass model : An analytically solvable model with a glass-to-glass transition

We present the detailed analysis of the spherical s+p spin-glass model with two competing interactions: among p spins and among s spins. The most interesting case is the 2+p model with p{>=}4 for

Equilibrium dynamics of spin-glass systems

We present a critical analysis of the Sompolinsky theory of equilibrium dynamics. By using the spherical 2+p spin-glass model we test the asymptotic static limit of the Sompolinsky solution showing

TAP approach for multi-species spherical spin glasses I: general theory

Abstract. We develop a generalized TAP approach for the multi-species version of the spherical mixed p-spin models. In particular, we prove a generalized TAP representation for the free energy at any
