论文摘要
本文概述了在材料本身的背景下,以及与高温超导(高$ T_C $)分层铜氧化物相比,分层稀土镍的多体(超过密度功能理论)电子结构的最新工作。它的目的是概述我们对分层镍的理解的当前状态,并展示对这些迷人材料的分析如何阐明现代电子结构理论中的基本问题。主要重点是确定如何估计并将其“将”“折叠”到低能理论中的相互作用物理学,该理论将描述$ \ sim 0.5 $ eV量表上相关的自由度,并且可以解决这些方法,并可以通过确定超导和旋转和电荷密度波相位界限,温度依赖性的电阻率和动力学的张紧能力和动力学的次数。
This article summarizes recent work on the many-body (beyond density functional theory) electronic structure of layered rare-earth nickelates, both in the context of the materials themselves and in comparison to the high-temperature superconducting (high-$T_c$) layered copper-oxide compounds. It aims to outline the current state of our understanding of layered nickelates and to show how the analysis of these fascinating materials can shed light on fundamental questions in modern electronic structure theory. A prime focus is determining how the interacting physics defined over a wide energy range can be estimated and "downfolded" into a low energy theory that would describe the relevant degrees of freedom on the $\sim 0.5$ eV scale and that could be solved to determine superconducting and spin and charge density wave phase boundaries, temperature-dependent resistivities, and dynamical susceptibilities.
