High-pressure modulation of breathing kagome lattice: Cascade of Lifshitz transitions and evolution of the electronic structure
Marcos V. Gonçalves-Faria, Maxim Wenzel, Yuk Tai Chan +12
The interplay between electronic correlations, density wave orders, and magnetism gives rise to several fascinating phenomena. In recent years, kagome metals have emerged as an exc…
Competition between spin-orbit coupling, magnetism, and dimerization in the honeycomb iridates: -LiIrO under pressure
V. Hermann, M. Altmeyer, J. Ebad-Allah +9
Single-crystal x-ray diffraction studies with synchrotron radiation on the honeycomb iridate -LiIrO reveal a pressure-induced structural phase transition with symmet…
High-pressure versus isoelectronic doping effect on the honeycomb iridate NaIrO
V. Hermann, J. Ebad-Allah, F. Freund +7
We study the effect of isoelectronic doping and external pressure in tuning the ground state of the honeycomb iridate NaIrO by combining optical spectroscopy with synchrotr…
Pressure dependence of the structure and electronic properties of Sr3Ir2O7
C. Donnerer, Z. Feng, J. G. Vale +9
We study the structural evolution of SrIrO as a function of pressure using x-ray diffraction. At a pressure of 54 GPa at room temperature, we observe a first-order stru…
Tuning the Eu valence in EuPd_3B_x: pressure versus valence electron count - a combined computational and experimental study
M. Schmitt, R. Gumeniuk, A. Trapananti +8
In a joint theoretical and experimental study we investigate the pressure dependence of the Eu valence in EuPd_3B_x (0 <= x <= 1). Density functional band structure calculations ar…
Two pressure-induced structural phase transitions in TiOCl
J. Ebad-Allah, A. Schönleber, S. van Smaalen +7
We studied the crystal structure of TiOCl up to pressures of =25~GPa at room temperature by x-ray powder diffraction measurements. Two pressure-induced structural phase transiti…
Deconfinement transition and dimensional crossover in the Bechgaard-Fabre salts: pressure- and temperature-dependent optical investigations
A. Pashkin, M. Dressel, M. Hanfland +1
The infrared response of the organic conductor (TMTSF)PF and the Mott insulator (TMTTF)PF are investigated as a function of temperature and pressure and for the pol…
Pressure-induced structural phase transition in the Bechgaard-Fabre salts
A. Pashkin, M. Dressel, S. G. Ebbinghaus +2
The crystal structures of the quasi-one-dimensional organic salts (TMTTF)PF and (TMTSF)PF were studied by pressure-dependent x-ray diffraction up to 10 GPa at room…
Mott-Hubbard gap closure and structural phase transition in the oxyhalides TiOBr and TiOCl under pressure
C. A. Kuntscher, A. Pashkin, H. Hoffmann +9
Pressure-dependent transmittance and reflectance spectra of TiOBr and TiOCl single crystals at room temperature suggest the closure of the Mott-Hubbard gap, i.e., the gap is filled…
Pressure-induced metallization and structural phase transition of the Mott-Hubbard insulator TiOBr
C. A. Kuntscher, S. Frank, A. Pashkin +9
We investigated the pressure-dependent optical response of the low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance measurements in the infrared and visibl…
Structural investigations on -FeGe at high pressure and low temperature
H. Wilhelm, M. Schmidt, R. Cardoso-Gil +4
The structural parameters of -FeGe have been determined at ambient conditions using single crystal refinement. Powder diffraction have been carried out to determine structural p…
