We review results concerning the critical behavior of spin systems at equilibrium. We
consider the Ising and the general O (N)-symmetric universality classes, including the N→ 0 …

Представлено описание особенностей неравновесного критического поведения
макроскопических систем, далёких от состояния равновесия, и изложены современные …

We solve a long-standing puzzle in statistical mechanics of disordered systems. By
performing a<? format?> high-statistics simulation of the D= 3 random-field Ising model at …

Owing to their intrinsic charge disorder ferroelectric crystals of strontium-barium-niobate
doped with Ce 3+ materialize the three-dimensional ferroic random-field Ising model (RFIM) …

Abstract We consider the Ginzburg-Landau MN model that describes M N-vector cubic
models with O (M)-symmetric couplings. We compute the renormalization-group functions to …

Universal and nonuniversal critical exponents of a three-dimensional Ising system with weak
quenched disorder are discussed. Experimental, computational, and theoretical results are …

By performing a high-statistics simulation of the D= 4 random-field Ising model at zero
temperature for different shapes of the random-field distribution, we show that the model is …

O 6 splits up into metastable polar nanoregions and paraelectric interfaces upon cooling …

The dielectric and ferroelectric switching properties of high temperature‐high energy density
(1− x) BaTiO 3-x BiScO 3 (0. 1⩽ x⩽ 0. 4) dielectrics were investigated over a broad …

Most physical and biological systems are disordered, even though the majority of theoretical
models treat disorder as a weak perturbation. One particularly simple system is a …
