ToF-PAX-RIXS: A Time-of-Flight Spectrometer for combined ARPES and RIXS
Chafic Fawaz, Tom Lacmannn, Yaryna Lytvynenko +24
We present ToF-PAX-RIXS, a compact instrument that combines time-of-flight momentum-microscopy angle-resolved photoemission spectroscopy (ARPES) with resonant inelastic X-ray scatt…
Ab Initio Investigation of Pressure Effects in the Spin-Liquid Candidate Y-Kapellasite
Federico Abbruciati, Aleksandar Razpopov, Joao Elias F. S. Rodrigues +5
Motivated by recent experiments showing pressure-induced suppression of magnetic order and the emergence of a dynamical ground state in the anisotropic kagome antiferromagnet Y-kap…
Intertwined Orders in a Quantum-Entangled Metal
Junyoung Kwon, Jaehwon Kim, Gwansuk Oh +18
Entanglement underpins quantum information processing and computing, yet its experimental quantification in complex, many-body condensed matter systems remains a considerable chall…
Chirality in the Kagome Metal CsVSb
H. J. Elmers, O. Tkach, Y. Lytvynenko +22
Using x-ray photoelectron diffraction (XPD) and angle-resolved photoemission spectroscopy, we study photoemission intensity changes related to changes in the geometric and electron…
Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
Disentangling lattice and electronic instabilities in the excitonic insulator candidate TaNiSe by nonequilibrium spectroscopy
Kota Katsumi, Alexandr Alekhin, Sofia-Michaela Souliou +7
TaNiSe is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below = 326 K. However, since a structural transi…
Direct observation of strong anomalous Hall effect and proximity-induced ferromagnetic state in SrIrO3
Arun Kumar Jaiswal, Di Wang, Vanessa Wollersen +3
The 5d iridium-based transition metal oxides have gained broad interest because of their strong spin-orbit coupling which favors new or exotic quantum electronic states. On the oth…
Electronic correlations in the van der Waals ferromagnet FeGeTe revealed by its charge dynamics
M. Corasaniti, R. Yang, K. Sen +5
The layered van der Waals ferromagnetic FeGeTe harbours an unconventional interplay between topology and magnetism, leading to a large anomalous Hall conductivity at low te…
Strange semimetal dynamics in SrIrO
Kaushik Sen, Dirk Fuchs, Rolf Heid +4
The interplay of electronic correlations, multi-orbital excitations, and strong spin-orbit coupling is a fertile ground for new states of matter in quantum materials. Here, we repo…
Complex magnetic order in nickelate slabs
Matthias Hepting, Robert J. Green, Zhicheng Zhong +18
Magnetic ordering phenomena have a profound influence on the macroscopic properties of correlated-electron materials, but their realistic prediction remains a formidable challenge.…
Site-selective Probe of Magnetic Excitations in Rare-earth Nickelates using Resonant Inelastic X-ray Scattering
Y. Lu, D. Betto, K. Fürsich +11
We have used high-resolution resonant inelastic x-ray scattering (RIXS) to study a thin film of NdNiO, a compound whose unusual spin- and bond-ordered electronic ground state h…
Raman scattering from Higgs mode oscillations in the two-dimensional antiferromagnet CaRuO
Sofia-Michaela Souliou, Jiří Chaloupka, Giniyat Khaliullin +5
We present and analyze Raman spectra of the Mott insulator CaRuO, whose quasi-two-dimensional antiferromagnetic order has been described as a condensate of low-lying spin-o…
Soft phonon driven orbital order in CaMn7O12
S. M. Souliou, Y. Li, X. Du +2
We use variable-temperature x-ray thermal diffuse scattering and inelastic scattering to investigate the lattice dynamics in single crystals of multiferroic CaMn7O12 which undergo…
Patterning of two-dimensional electron systems in SrTiO3 based heterostructures using a CeO2 template
D. Fuchs, K. Wolff, R. Schäfer +3
Two-dimensional electron systems found at the interface of SrTiO3-based oxide heterostructures often display anisotropic electric transport whose origin is currently under debate.…
