A rich correlated electronic structure in line with recent experimental investigations is revealed by the given realistic many-body approach to a large-unit-cell oxide heterostructure. Coexistence of conducting and Mott-insulating TiO2 layers prone to magnetic order gives rise to multi-orbital electronic transport beyond standard Fermi-liquid theory. First hints towards a pseudogap opening due to electron-electron scattering within a background of ferromagnetic and antiferromagnetic fluctuations are detected.en2045-232220171Article number: 1565 (2017)Nature Publishing Grouphttps://creativecommons.org/licenses/by/4.0/Mott-insulating distorted perovskite SmTiO3dynamical mean-field theoryelectron-electron scatteringantiferromagnetic fluctuationsPhysikJournal Articleurn:nbn:de:gbv:830-8822294810.15480/882.176711420/177010.1038/s41598-017-01847-510.15480/882.1767Other
