Diluted random fields in Mixed cyanide crystals
A percolation argument and a dilute compressible random field Ising model are used to present a simple model for mixed cyanide crystals. The model reproduces quantitatively several features of the phase diagrams altough some crude approximations are made. In particular critical thresholds xc at which ferroelastic first order transitions disappear, are calculated. Moreover, transitions are found...
متن کاملMixed cyanide crystals
A model of diluted random field sustained by quenched volume deformations is shown to reproduce puzzling physical features found in X(CN)xY1−x mixed cyanide crystals. X is an alkali metal (K, Na or Rb) and Y is a spherical halogen ion (Br, Cl or I). Critical thresholds xc at which associated first order ferroelastic transitions disappear are calculated exactly. The diluted random field is shown...
متن کاملDiluted Generalized Random Energy Model
We introduce a layered random spin model, equivalent to the Generalized Random Energy Model (GREM) for some range of parameters. Similarly to diluted spin system, the diluted GREM (DGREM) is introduced. It can be applied to calculate approximatly thermodynamical properties of spin glass models in low dimensions. Derrida’s Random Energy Model (REM) [1] is becoming more and more popular. It has b...
متن کاملRandom Multi-Overlap Structures and Cavity Fields in Diluted Spin Glasses
We introduce the concept of Random Multi-Overlap Structure (RaMOSt) as a generalization of the one introduced by M. Aizenman R. Sims and S. L. Starr for non-diluted spin glasses. We use such method to find generalized bounds for the free energy of the Viana-Bray model of diluted spin glasses and to formulate and prove the Extended Variational Principle that implicitly provides the free energy o...
متن کاملRandom Projection-Based Anderson-Darling Test for Random Fields
In this paper, we present the Anderson-Darling (AD) and Kolmogorov-Smirnov (KS) goodness of fit statistics for stationary and non-stationary random fields. Namely, we adopt an easy-to-apply method based on a random projection of a Hilbert-valued random field onto the real line R, and then, applying the well-known AD and KS goodness of fit tests. We conclude this paper by studying the behavior o...
