我们研究最近提出的理论的中温pseudogap金属相的铜酸盐的光谱特性。我们表明,这个理论可以从熟悉的顺磁理论的近反铁磁金属的顺磁分裂成两个“隐藏”层的自旋。第一个隐藏层的自旋与电子杂交,就像在近藤晶格重费米液体中一样,而第二个隐藏层的自旋形成了一种具有分数自旋子激发的自旋液体。计算了自旋激发引起的电子自能的虚部。能量和动量的依赖性的光电子能谱的布里渊区提供了一个很好的匹配,观察等。[Science 331,1579(2011)SCIEAS0036-807510.1126/science.1198415] Chenet al.

We examine spectral properties of a recently proposed theory of the intermediate temperature pseudogap metal phase of the cuprates. We show that this theory can be obtained from the familiar paramagnon theory of nearly antiferromagnetic metals by fractionalizing the paramagnon into two “hidden” layers ofspins. The first hidden layer of spins hybridizes with the electrons as in a Kondo lattice heavy Fermi liquid, whereas the second hidden layer of spins forms a spin liquid with fractionalized spinon excitations. We compute the imaginary part of the electronic self-energy induced by the spinon excitations. The energy and momentum dependence of the photoemission spectrum across the Brillouin zone provides a good match to observations by Heet al.[Science 331, 1579 (2011)SCIEAS0036-807510.1126/science.1198415] inand by Chenet al.[Science 366, 1099 (2019)SCIEAS0036-807510.1126/science.aaw8850] in.
