Anomalous 4 fine structure in TmSeTe across the metal-insulator transition
C. -H. Min, S. Müller, W. J. Choi +17
Hybridization between localized 4 and itinerant 56 states in heavy fermion compounds is a well-studied phenomenon and commonly captured by the paradigmatic Anderson model.…
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…
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…
Momentum-space signatures of Berry flux monopoles in a Weyl semimetal
M. Ünzelmann, H. Bentmann, T. Figgemeier +14
Since the early days of Dirac flux quantization, magnetic monopoles have been sought after as a potential corollary of quantized electric charge. As opposed to magnetic monopoles e…
Oxide Fermi liquid universality revealed by electron spectroscopy
M. Horio, K. P. Kramer, Q. Wang +27
We present a combined soft x-ray and high-resolution vacuum-ultraviolet angle-resolved photoemission spectroscopy study of the electron-overdoped cuprate PrLaCe$_…
Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators
Thiago R. F. Peixoto, Hendrik Bentmann, Philipp Rüßmann +27
Since the discovery of the quantum anomalous Hall effect in the magnetically doped topological insulators (MTI) Cr:(Bi,Sb)Te and V:(Bi,Sb)Te, the search for the exc…
Ultrafast doublon dynamics in photo-excited 1T-TaS
Manuel Ligges, Isabella Avigo, Denis Golež +8
Strongly correlated systems exhibit intriguing properties caused by intertwined microscopic in- teractions that are hard to disentangle in equilibrium. Employing non-equilibrium ti…
Ultrafast melting of a charge-density wave in the Mott insulator 1T-TaS2
S. Hellmann, M. Beye, C. Sohrt +11
Femtosecond time-resolved core-level photoemission spectroscopy with a free-electron laser is used to measure the atomic-site specific charge-order dynamics in the charge-density-w…
