超越费米液体范式:隐藏的费米液体

Beyond the Fermi Liquid Paradigm: Hidden Fermi Liquids

J. K. Jain, P. W. Anderson

摘要:

在过去的四分之一世纪中发现的两个最有趣的现象,即高温超导性和分数量子霍尔效应,激发了对物质可能的非费米液态的深入研究。尽管在概念上取得了巨大的进步,但这两个领域在很大程度上是沿着不同的道路发展的。两个广泛应用的理论是高温超导的共振价键理论和分数量子霍尔效应的复合费米子理论。这篇“透视”文章的目的是指出,它们都遵循一个共同的基本范式:它们都将这些奇异的量子液体与非物理希尔伯特空间中的某些普通费米液体联系起来。这样的关系产生了许多重要的实验结果,使这些理论受到严格和明确的检验。

英文摘要:

An intense investigation of possible non-Fermi liquid states of matter has been inspired by two of the most intriguing phenomena discovered in the past quarter century, namely high temperature superconductivity and the fractional quantum Hall effect. Despite enormous conceptual strides, these two fields have developed largely along separate paths. Two widely employed theories are the resonating valence bond theory for high temperature superconductivity and the composite fermion theory for the fractional quantum Hall effect. The goal of this "perspective" article is to note that they subscribe to a common underlying paradigm: they both connect these exotic quantum liquids to certain ordinary Fermi liquids residing in unphysical Hilbert spaces. Such a relation yields numerous nontrivial experimental consequences, exposing these theories to rigorous and definitive tests.
