Spin polarization of the two-dimensional electron gas at the EuO/SrTiO interface
Paul Rosenberger, Andri Darmawan, Olena Fedchenko +10
Spin-polarized two-dimensional electron gases (2DEGs) are of particular interest for functional oxide electronics applications. The redox-created 2DEG residing on the strontium tit…
High-accuracy Measurements of Core-excited Transitions in Light Li-like Ions
Moto Togawa, Steffen Kühn, Chintan Shah +11
The transition energies of the two -core-excited soft X-ray lines (dubbed q and r) from to the respective upper levels an…
Chirality-Driven Orbital Angular Momentum and Circular Dichroism in CoSi
Stefanie Suzanne Brinkman, Xin Liang Tan, Bjørnulf Brekke +15
Chiral crystals and molecules were recently predicted to form an intriguing platform for unconventional orbital physics. Here, we report the observation of chirality-driven orbital…
Natural-linewidth measurements of the 3C and 3D soft-x-ray transitions in Ni XIX
Chintan Shah, Steffen Kühn, Sonja Bernitt +15
We used the monochromatic soft-x-ray beamline P04 at the synchrotron-radiation facility PETRA III to resonantly excite the strongest transitions in neon-like Ni XIX ions, $…
A compact approach to higher-resolution resonant inelastic X-ray scattering detection using photoelectrons
Jan O. Schunck, Jens Buck, Robin Y. Engel +11
The detection of inelastically scattered soft X-rays with high energy resolution usually requires large grating spectrometers. Recently, photoelectron spectrometry for analysis of…
Tomographic Imaging of Orbital Vortex Lines in Three-Dimensional Momentum Space
T. Figgemeier, M. Ünzelmann, P. Eck +16
We report the experimental discovery of orbital vortex lines in the three-dimensional (3D) band structure of a topological semimetal. Combining linear and circular dichroism in sof…
