TLDR
In this article, it was shown that when the order parameter has a continuous symmetry, the ordered state is unstable against an arbitrarily weak random field in less than four dimensions and the borderline dimensionality above which mean-field-theory results hold is six.Abstract:
Phase transitions are considered in systems where the field conjugate to the order parameter is static and random. It is demonstrated that when the order parameter has a continuous symmetry, the ordered state is unstable against an arbitrarily weak random field in less than four dimensions. The borderline dimensionality above which mean-field-theory results hold is six. (auth)read more

On Larkin-Imry-Ma State of 3He-A in Aerogel
TL;DR: In this article, the Larkin-Imry-Ma effect was studied in the case of a doubly anisotropic superfluid 3He-A with random anisotropy disorder.

Random-field models for relaxor ferroelectric behavior
TL;DR: In this paper, a four-state clock model with a type of random field on simple cubic lattices is studied, where the two random-field Ising model components are coupled and a large peak in the structure factor appears at small k for temperatures well above the transition to long-range order.

Interplay between Chain Collapse and Microphase Separation in Bottle-Brush Polymers with Two Types of Side Chains
TL;DR: In this article, the conformations of a bottle-brush polymer with two types (A,B) of grafted side chains are studied by molecular dynamics simulations, using a coarse-grained bead−spring model with side chains of up to...

TL;DR: It is argued that ergodicity is restored in dimension d>1, although equilibration should be extremely slow, similar to the dynamics of glasses.

Temperature-Dependent Magnetic Response of Antiferromagnetic Doping in Cobalt Ferrite Nanostructures
TL;DR: It is shown that magnetic properties have been tuned as a function of temperature and an externally-applied field.
