Covalent bonding and the nature of band gaps in some half-Heusler compounds
Hem Chandra Kandpal, Claudia Felser, Ram Seshadri
Half-Heusler compounds \textit{XYZ}, also called semi-Heusler compounds, crystallize in the MgAgAs structure, in the space group . We report a systematic examination of b…
Do we Observe Quantum Gravity Effects at Galactic Scales?
M. Reuter, H. Weyer
The nonperturbative renormalization group flow of Quantum Einstein Gravity (QEG) is reviewed. It is argued that there could be strong renormalization effects at large distances, in…
Structure and transport properties of amorphous aluminium silicates: computer simulation studies
Patrick Pfleiderer, Juergen Horbach, Kurt Binder
The structure and transport properties of SiO2-Al2O3 melts containing 13 mol% and 47 mol% Al2O3 are investigated by means of large scale molecular dynamics computer simulations. Th…
Selfish vs. Unselfish Optimization of Network Creation
Johannes J. Schneider, Scott Kirkpatrick
We investigate several variants of a network creation model: a group of agents builds up a network between them while trying to keep the costs of this network small. The cost funct…
Instability of Equilibrium States for Coupled Heat Reservoirs at Different Temperatures
M. Merkli, M. Mück, I. M. Sigal
We consider quantum systems consisting of a ``small'' system coupled to two reservoirs (called open systems). We show that such a system has no equilibrium states normal with respe…
Unusual quasi-one-dimensional electron dispersions in the spin-1/2 quantum magnet TiOCl
M. Hoinkis, M. Sing, J. Schaefer +8
We have studied the electronic structure of the spin-1/2 quantum magnet TiOCl by polarization-dependent momentum-resolved photoelectron spectroscopy. From that, we confirm the quas…
