Direct Observation of Orbital Hybridisation in a Cuprate Superconductor
Nature communications, 2018Co-Authors: Christian Matt, D Sutter, A M Cook, Y Sassa, Martin Mansson, Oscar Tjernberg, L Das, M Horio, D Destraz, C G FatuzzoAbstract:The minimal ingredients to explain the essential physics of layered copper-oxide (cuprates= materials remains heavily debated. Effective low energy single-band models of the copper-oxygen Orbitals are widely used because there exists no strong experimental evidence supporting multiband structures. Here we report angle-resolved photoelectron spectroscopy experiments on La-based cuprates that provide direct observation of a two-band structure. This electronic structure, qualitatively consistent with density functional theory, is parametrised by a two-Orbital ($d_{x^2-y^2}$ and $d_{z^2}$) tight-binding model. We quantify the Orbital Hybridisation which provides an explanation for the Fermi surface topology and the proximity of the van-Hove singularity to the Fermi level. Our analysis leads to a unification of electronic hopping parameters for single-layer cuprates and we conclude that Hybridisation, restraining d-wave pairing, is an important optimisation element for superconductivity.
