Abstract

For a number of quantum critical points in one dimension quantum field theory has provided exact results for the scaling of spatial and temporal correlation functions. Experimental realizations of these models can be found in certain quasi one dimensional antiferromagnetic materials. Measuring the predicted scaling laws experimentally presents formidable technical challenges. In many cases it only became possible recently, thanks to qualitative progress in the development of inelastic neutron scattering techniques and to the discovery of new model compounds. Here we review some of the recent experimental studies of this type.

一维反铁磁体的量子临界动力学和定标

摘要

对于一维中的多个量子临界点,量子场论为空间和时间相关函数的缩放提供了精确的结果。这些模型的实验实现可以在某些准一维反铁磁材料中找到。实验上测量预测的缩放定律提出了巨大的技术挑战。在许多情况下,由于非弹性中子散射技术的发展取得了质的进展以及新的模型化合物的发现,直到最近才有可能。在这里,我们回顾一些这种类型的最新实验研究。
