Critical behavior of the Coulomb-glass model in the zero-disorder limit: Ising universality in a system with long-range interactions
A. Mobius, U. K. Roessler
The ordering of charges on half-filled hypercubic lattices is investigated numerically, where electroneutrality is ensured by background charges. This system is equivalent to the $…
Lifshitz transitions and elastic properties of Osmium under pressure
Daniela Koudela, Manuel Richter, Arnulf Mobius +2
Topological changes of the Fermi surface under pressure may cause anomalies in the low-temperature elastic properties. Our density functional calculations for elemental Osmium evid…
Short-range type critical behavior in spite of long-range interactions: the phase transition of a Coulomb system on a lattice
A. Mobius, U. K. Roessler
One- to three-dimensional hypercubic lattices half-filled with localized particles interacting via the long-range Coulomb potential are investigated numerically. The temperature de…
Possible persistence of the metal-insulator transition in two-dimensional systems at finite temperatures
A. Mobius
For the immediate vicinity of the metal-insulator transition (MIT), data on the dependence of the resistivity rho on the charge carrier concentration n from an Si MOSFET experiment…
Combinatorial Optimization by Iterative Partial Transcription
A. Mobius, B. Freisleben, P. Merz +1
A procedure is presented which considerably improves the performance of local search based heuristic algorithms for combinatorial optimization problems. It increases the average `g…
