Electronic and phononic properties of cinnabar: ab initio calculations and some experimental results
M. Cardona, R. K. Kremer, R. Lauck +4
We report ab initio calculations of the electronic band structure, the corresponding optical spectra, and the phonon dispersion relations of trigonal alpha-HgS (cinnabar). The calc…
Curvature effect on the interaction between folded graphitic surface and silver clusters
A. F. Kemper, H-P. Cheng, N. Kébaïli +4
Evidence of curvature effects on the interaction and binding of silver clusters on folded graphitic surfaces has been shown from both experiment and theory. Density Functional Theo…
Understanding the insulating phase in CMR manganites: Shortening of the Jahn-Teller long-bond across the phase diagram of La_{1-x} Ca_x Mn O_3
E. S. Bozin, M. Schmidt, A. J. DeConinck +6
The detailed evolution of the magnitude of the local Jahn-Teller (JT) distortion in La_{1-x} Ca_x Mn O_3 is obtained across the phase diagram for 0 < x < 0.5 from high quality neut…
Spin singlet formation in MgTiO: evidence of a helical dimerization pattern
M. Schmidt, W. Ratcliff, P. G. Radaelli +3
The transition metal spinel MgTiO undergoes a metal-insulator transition on cooling below K. A sharp reduction of the magnetic susceptibility below $T_{M-I}…
Temperature-induced barium de-trapping from a double-well potential in Ba6Ge25
M. Schmidt, P. G. Radaelli, M. J. Gutmann +3
The crystal structure of barium-germanium clathrate Ba6Ge25 was studied using neutron powder diffraction in the temperature range 20-300K. The compound was found to be cubic (S.G.…
Colloid-Induced Polymer Compression
A. R. Denton, M. Schmidt
We consider a model mixture of hard colloidal spheres and non-adsorbing polymer chains in a theta solvent. The polymer component is modelled as a polydisperse mixture of effective…
