Coherent Order Parameter Oscillations in the Ground State of the Excitonic Insulator Ta2NiSe5
Daniel Werdehausen, Tomohiro Takayama, Marc Höppner +6
The excitonic insulator is an intriguing electronic phase of quasi-condensed excitons. A prominent candidate is the small bandgap semiconductor Ta2NiSe5, in which excitons are beli…

Optical anisotropy of the Jeff = 1/2 Mott insulator Sr2IrO4
D. Pröpper, A. N. Yaresko, M. Höppner +7
We report the complex dielectric function along and perpendicular to the IrO2 planes in the layered perovskite Sr2IrO4 determined by spectroscopic ellipsometry in the spectral rang…
