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

Multiferroic clusters: a new perspective for relaxor-type room-temperature multiferroics

TL;DR: In this paper, a relaxor ferroelectric single-phase material was proposed, where polar nanoregions (PNR) transform into static-PNR and simultaneously enable congruent multiferroic clusters (MFC) to emerge from inherent ferrimagnetic Bi(Fe,Co)O3 regions as verified by magnetic force microscopy (MFM) and secondary ion mass spectrometry (SIMS).

Critical fluctuations at a many-body exceptional point
TL;DR: In this article, a non-Hermitian class of dynamic critical phenomenon beyond the classification by Hohenberg and Halperin triggered by the coalescence of the collective eigenmodes to the Goldstone mode is proposed.
