Nature of the current-induced insulator-to-metal transition in CaRuO as revealed by transport-ARPES

Cissy T Suen, Igor Marković, Marta Zonno +21

The Mott insulator CaRuO exhibits a rare insulator-to-metal transition (IMT) induced by DC current. While structural changes associated with this transition have been track…

A new benchmark of soft X-ray transition energies of Ne, CO, and SF: paving a pathway towards ppm accuracy

J. Stierhof, S. Kühn, M. Winter +24

A key requirement for the correct interpretation of high-resolution X-ray spectra is that transition energies are known with high accuracy and precision. We investigate the K-shell…

Charge disproportionation and nano phase separation in SrNiO

H. Guo, Z. W. Li, C. F. Chang +16

We have successfully grown centimeter-sized layered SrNiO single crystals under high oxygen pressures of 120 bar by the floating zone technique. This enabled us to perform n…

Bands, resonances, edge singularities and excitons in core level spectroscopy investigated within the dynamical mean field theory

M. W. Haverkort, G. Sangiovanni, P. Hansmann +3

Using a recently developed impurity solver we exemplify how dynamical mean field theory captures band excitations, resonances, edge singularities and excitons in core level x-ray a…

Effective crystal field and Fermi surface topology: a comparison of d- and dp-orbital models

N. Parragh, G. Sangiovanni, P. Hansmann +3

The effective crystal field in multi-orbital correlated materials can be either enhanced or reduced by electronic correlations with crucial consequences for the topology of the Fer…

Orbital characters of three-dimensional Fermi surfaces in Eu2-xSrxNiO4 as probed by soft-x-ray angle-resolved photoemission spectroscopy

M. Uchida, K. Ishizaka, P. Hansmann +13

The three-dimensional Fermi surface structure of hole-doped metallic layered nickelate Eu2-xSrxNiO4 (x=1.1), an important counterpart to the isostructural superconducting cuprate L…
