Rounding effects of quenched randomness on first-order phase transitions

TL;DR: In this paper, it was shown that the Gibbs state is unique for almost all field configurations, and that the vanishing of the latent heat at the transition point can be explained by the randomness in dimensions d ≥ 4.
Journal ArticleDOI

Collective properties of neural networks: A statistical physics approach

P. Peretto
TL;DR: In this article, the storage capacity of neural networks working along with the Little dynamics is shown to be similar to the capacity of Hopfield neural networks, which is a more realistic description of the biological situation.
Journal ArticleDOI

Absence of self-averaging of the order parameter in the Sherrington-Kirkpatrick model

TL;DR: In this article, it was shown that the variance of the free energy of the Sherrington-Kirkpatrick (SK) model converges to zero as n→∞.
Journal ArticleDOI

The replica-symmetric solution without replica trick for the Hopfield model

TL;DR: In this article, the saddle point equations for the Hopfield model were derived in the case of replica symmetry without using the replica trick, but assuming that the Edwards-Anderson parameter is a self-averaging quantity.
Journal ArticleDOI

Existence of free energy for models with long-range random Hamiltonians

TL;DR: In this article, the free energy of a classical lattice system with random Hamiltonians was shown to exist with probability 1 and does not depend on the boundary conditions, provided α > 1/2.

Introduction to Phase Transitions and Critical Phenomena

TL;DR: In this article, the authors present a paperback edition of a distinguished book, originally published by Clarendon Press in 1971, which is at the level at which a graduate student who has studied condensed matter physics can begin to comprehend the nature of phase transitions, which involve the transformation of one state of matter into another.

Solvable Model of a Spin-Glass

TL;DR: In this article, an Ising model in which the spins are coupled by infinite-ranged random interactions independently distributed with a Gaussian probability density is considered and the competition between the phases and the type of order present in each is studied.
Journal ArticleDOI

Theory of spin glasses

TL;DR: In this paper, a new theory of spin glasses is proposed, which offers a simple explanation of the cusp found experimentally in the susceptibility, which is smoothed by an external field.

Magnetic Ordering in Gold-Iron Alloys

TL;DR: In this paper, the temperature dependences of the thermoelectric power and the low-field magnetic susceptibility for Fe alloys were made of the temperature dependent on the temperature.
