Band-like/atomic-like duality of dd excitations in cuprates

The fascinating properties of high Tc superconducting cuprates are often attributed to the peculiar entwining of sev-eral degrees of freedom (charge density and anisotropy,...高温超导铜基氧化物（high Tc superconducting cuprates）所展现的诸多迷人特性，通常被归因于多种自由度（degrees of freedom）——即电荷密度（charge density）与各向异性（anisotropy）等——之间独特的交织缠结。
