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…

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…
