Dissolution Behavior of Fe from CaO-SiO₂-FeO_x Glassy Phase

Glassy behavior of a homopolymer from molecular dynamics simulations.

We study at- and out-of-equilibrium dynamics of a single homopolymer chain at low temperature using molecular dynamics. The main quantities of interest are the average root mean square displacement of the monomers below the theta point, and the structure factor, as a function of time. The observation of these quantities show a close resemblance to those measured in structural glasses and sugges...

Glassy Behavior of Random Field Magnets

The key unresolved feature of the random eld Ising model is the complex, history dependent behavior found both in experiments and numerical simulations. It appears that for strong enough disorder, and low temperatures, the system falls out of equilibrium, displaying anomalously slow relaxation and other features characteristic of glassy materials. Recently, it has been proposed that this behavi...

Origin of the glassy magnetic behavior of the phase segregated state of the perovskites.

In this Letter we demonstrate that the phase segregated state observed in many rare-earth perovskites constitutes a sort of self-generated assembly of magnetic clusters in which magnetic interaction introduces collectivity among them. We show that the observed glassy behavior (memory, aging, etc.) can be perfectly understood taking into account only the intercluster interactions. We address the...

Kinetics of spinel formation and growth during dissolution of MgO in CaO-Al2O3-SiO2 slag

The glassy phase of Gallager codes

Gallager codes are the best error-correcting codes to-date. In this paper we study them by using the tools of statistical mechanics. The corresponding statistical mechanics model is a spin model on a sparse random graph. The model can be solved by elementary methods (i.e. without replicas) in a large connectivity limit. For low enough temperatures it presents a completely frozen glassy phase (q...
