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

Probing local polar structures in PZN-xPT and PMN-xPT relaxor ferroelectrics with neutron and x-ray scattering
TL;DR: In this paper, the authors used neutron scattering and x-ray diffraction to probe the properties of polar nano-regions in two prototypical lead-based perovskite relaxor systems Pb(Zn1/3Nb2/3)O3 (PZN) and PMN (PMN).

Effect of random field disorder on the first order transition in p-spin interaction model
Sumedha,Sushant K. Singh +1 more
TL;DR: In this article, the authors studied the effect of quenched random field on systems which have a sharp first order transition in the pure state and found that the magnetic susceptibility for p ≥ 3 is discontinuous at the transition point for h h o.

TL;DR: In this article, the authors report the discovery of an alternative route for metal-to-insulator transitions driven by the creation of a network of narrow channels, where the charges confined to the narrow DWs interact strongly, with pseudogap-like suppression in the local density of states.

Tunneling in two dimensional QCD
TL;DR: In this article, the existence of a critical area is encoded in the winding Wilson loops, and the dynamics of these loops consists of two smoothly connected domains separated by the critical area, one domain with a confining behavior for large winding Wilson loop, and one (below the critical size) where the string tension disappears.

Low-energy excitations in the three-dimensional random-field Ising model
TL;DR: In this paper, the authors extended the ground-state algorithm by various methods in order to analyze low-energy excitations for the three-dimensional RFIM with Gaussian distributed disorder that appear in the form of clusters of connected spins.
