全息非费米液体不动点

Holographic non-Fermi liquid fixed points

Thomas Faulkner, Nabil Iqbal, Hong Liu, John McGreevy, David Vegh

摘要:

源自弦论的技术可以用来研究强相互作用费米子的集合。通过这种“全息对偶”,各种强耦合的多体系统使用引力的辅助理论来解决。有限密度的简单全息实现呈现出具有尖锐费米面的单粒子谱函数,其形式与朗道理论的形式不同。红外不动点理论中的自能由一个关联函数给出,而红外不动点理论中的自能由一个AdS_2区域表示。在这里,我们详细描述了这个IR关联函数的重力计算。这篇文章是对菲尔特刊的贡献。Trans. A上的铜酸盐的正常状态;因此,我们也提供了一些审查和背景。

英文摘要:

Techniques arising from string theory can be used to study assemblies of strongly-interacting fermions. Via this `holographic duality', various strongly-coupled many body systems are solved using an auxiliary theory of gravity. Simple holographic realizations of finite density exhibit single-particle spectral functions with sharp Fermi surfaces, of a form distinct from those of the Landau theory. The self-energy is given by a correlation function in an infrared fixed point theory which is represented by an AdS_2 region in the dual gravitational description. Here we describe in detail the gravity calculation of this IR correlation function. This article is a contribution to a special issue of Phil. Trans. A on the normal state of the cuprates; as such, we also provide some review and context.
