The quantum many-body problem of correlated electrons is a frontier topic in condensed matter physics and dominates the study of metals and superconductors. Layered 4d transition metal oxides (TMOs) based on ruthenium and rhodium ions are particularly attractive systems to study this problem because they can be grown with unrivaled purity and exhibit a wealth of subtle quantum many-body states. It is proposed to investigate such states by angular resolved photoemission (ARPES). This will provide new insight into fundamental questions underlying the physics of 4d TMOs and may shed light on a variety of poorly understood phases in cuprates and manganites.

相关电子的量子多体问题是凝聚态物理中的一个前沿问题，在金属和超导体的研究中占主导地位。基于钌和铑离子的层状四维过渡金属氧化物（TMOs）是研究这个问题特别有吸引力的系统，因为它们可以以无与伦比的纯度生长，并表现出丰富的微妙量子多体态。提出了用角分辨光发射（ARPES）来研究这些态的方法。这将为4d TMOs物理学的基本问题提供新的见解，并可能阐明铜酸盐和锰酸盐中各种尚不清楚的相。
