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

Compositional heterogeneity and the origins of the multicell cubic state in Sn‐doped lead zirconate titanate ceramics
TL;DR: In this article, a systematic study of Sn-doped lead zirconate titanate ceramics has been carried out as a function of Sn and Ti contents, and the dielectric constant and remanent polarization measurements have been performed and compared to our recent transmission electron microscopy study.

Fractional and integer quantum Hall effects in the zeroth Landau level in graphene
TL;DR: In this paper, the energy gap at integer fillings ν = 0a ndν =− 1, as a function of magnetic field, and the possibility that valley skyrmions may account for the smaller energy gaps observed at ν=− 1.

Modulated phases, memory effect and defect density waves in thiourea
TL;DR: In this article, a variety of recent experimental and theoretical results on thiourea, a compound known for the richness of its phase diagram, are reviewed, and a continuum approach is particularly well suited to understand the modulated phases and the commensurate lock-ins in this compound.

Quantum engine based on many-body localization
TL;DR: In this paper, an athermality of many-body-localized (MBL) systems is harnessed for thermodynamic tasks, and an Otto engine cycle for a quantum MBL system is proposed.
