Dynamics of electronic states in the insulating Intermediate surface phase of 1T-TaS
Jingwei Dong, Weiyan Qi, Dongbin Shin +14
This article reports a comparative study of bulk and surface properties in the transition metal dichalcogenide 1T-TaS. When heating the sample, the surface displays an intermed…
Electronic dispersion, correlations and stacking in the photoexcited state of 1T-TaS
Jingwei Dong, Dongbin Shin, Ernest Pastor +11
Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
Pressure-tuning of -RuCl towards the ideal Kitaev-limit
Quirin Stahl, Tobias Ritschel, Gaston Garbarino +4
We report the discovery of an intriguing pressure-driven phase transformation in the layered Kitaev-material -RuCl. By analyzing both the Bragg scattering as well as the dif…
Temperature-driven reorganization of electronic order in CsVSb
Q. Stahl, D. Chen, T. Ritschel +3
We report a temperature dependent x-ray diffraction study of the electronic ordering instabilities in the kagome material CsVSb. Our measurements between 10 K and 120 K rev…
Hidden Charge Order in an Iron Oxide Square-Lattice Compound
Jung-Hwa Kim, Darren C. Peets, Manfred Reehuis +14
Since the discovery of charge disproportionation in the FeO square-lattice compound SrFeO by Mössbauer spectroscopy more than fifty years ago, the spatial ordering…
Collapse of layer dimerization in the photo-induced hidden state of 1T-TaS2
Quirin Stahl, Maximilian Kusch, Florian Heinsch +6
Photo-induced switching between collective quantum states of matter is a fascinating rising field with exciting opportunities for novel technologies. Presently very intensively stu…
Disrupted orbital order and the pseudo-gap in layered 1T-TaS
Tobias Ritschel, Helmuth Berger, Jochen Geck
We present a state-of-the-art density functional theory (DFT) study which models crucial features of the partially disordered orbital order stacking in the prototypical layered tra…
The effect of different in-chain impurities on the magnetic properties of the spin chain compound SrCuO probed by NMR
Yannic Utz, Franziska Hammerath, Roberto Kraus +14
The S=1/2 Heisenberg spin chain compound SrCuO2 doped with different amounts of nickel (Ni), palladium (Pd), zinc (Zn) and cobalt (Co) has been studied by means of Cu nuclear magne…
Ba2YIrO6: A cubic double perovskite material with Ir5+ ions
T. Dey, A. Maljuk, D. V. Efremov +13
Materials with a 5d4 electronic configuration are generally considered to have a nonmagnetic ground state (J=0). Interestingly, Sr2YIrO6 (Ir5+ having 5d4 electronic configuration)…
Orbital textures and charge density waves in transition metal dichalcogenides
T. Ritschel, J. Trinckauf, K. Koepernik +6
Low-dimensional electron systems, as realized naturally in graphene or created artificially at the interfaces of heterostructures, exhibit a variety of fascinating quantum phenomen…
Pressure dependence of the charge density wave in 1T-TaS2 and its relation to superconductivity
T. Ritschel, J. Trinckauf, G. Garbarino +5
We present a state-of-the-art x-ray diffraction study of the charge density wave order in 1T-TaS2 as a function of temperature and pressure. Our results prove that the charge densi…
Electronic confinement and ordering instabilities in colossal magnetoresistive bilayer manganites
