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

Renewal sequences, disordered potentials, and pinning phenomena
TL;DR: In this article, the authors give an overview of the state of the art of the analysis of disordered models of pinning on a defect line, including a number of well-known and much studied systems, such as polymer pinning, wetting of interfaces on a disordered substrate and DNA denaturation.

Chaotic Quantization of Classical Gauge Fields
TL;DR: In this article, it was shown that the quantized non-Abelian gauge theory can be obtained as the infrared limit of the corresponding classical gauge theory in a higher dimension.

Random field Ising model : statistical properties of low-energy excitations and of equilibrium avalanches
Cécile Monthus,Thomas Garel +1 more
TL;DR: In this article, the authors studied the statistics of low-energy excitations generated by an imposed single spin-flip with respect to the ground state, as well as the statistic of equilibrium avalanches, i.e. the magnetization jumps that occur in the sequence of ground states as a function of the external magnetic field.

Multiple Charge Density Waves and Superconductivity Nucleation at Antiphase Domain Walls in the Nematic Pnictide Ba 1 − x Sr x Ni 2 As 2

TL;DR: In this article, a new charge density wave (CDW) was discovered in a charge ordered pnictide superconductor (BSNA), which was shown to exhibit a sixfold enhancement of superconductivity due to nematic fluctuations near a quantum phase transition.

Statistical mechanics of coupled supercooled liquids in finite dimensions
TL;DR: In this article, the authors studied the statistical mechanics of supercooled liquids when the system evolves at a temperature $T$ with a linear coupling of amplitude $\epsilon$ to its overlap with a reference configuration of the same liquid sampled at a higher temperature.
