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…
Heat conductivity of the spin-Peierls compounds TiOCl and TiOBr
N. Hlubek, M. Sing, S. Glawion +5
We report experimental results on the heat conductivity κof the S=1/2 spin chain compounds TiOBr and TiOCl for temperatures 5K<T<300K and magnetic fields up to 14. Surprisingly, we…
Electronic structure of the two-dimensional Heisenberg antiferromagnet VOCl: a multi-orbital Mott insulator
S. Glawion, M. R. Scholz, Y. -Z. Zhang +7
We have studied the electronic structure of the two-dimensional Heisenberg antiferromagnet VOCl using photoemission spectroscopy and density functional theory including local Coulo…
Photoemission of a doped Mott insulator: spectral weight transfer and qualitative Mott-Hubbard description
M. Sing, S. Glawion, M. Schlachter +5
The spectral weight evolution of the low-dimensional Mott insulator TiOCl upon alkali-metal dosing has been studied by photoelectron spectroscopy. We observe a spectral weight tran…
Momentum-resolved single-particle spectral function for TiOCl from a combination of density functional and variational cluster calculations
M. Aichhorn, T. Saha-Dasgupta, R. Valenti +3
We present results for the momentum-resolved single-particle spectral function of the low-dimensional system TiOCl in the insulating state, obtained by a combination of ab initio D…
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…
Are the renormalized band widths in TTF-TCNQ of structural or electronic origin? - An angular dependent NEXAFS study
M. Sing, J. Meyer, M. Hoinkis +5
We have performed angle-dependent near-edge x-ray absorption fine structure measurements in the Auger electron yield mode on the correlated quasi-one-dimensional organic conductor…
Cluster Dynamical Mean-field calculations for TiOCl
T. Saha-Dasgupta, A. Lichtenstein, M. Hoinkis +4
Based on a combination of cluster dynamical mean field theory (DMFT) and density functional calculations, we calculated the angle-integrated spectral density in the layered …
One-dimensional versus two-dimensional correlation effects in the oxyhalides TiOCl and TiOBr
