The metal-insulator transition in disordered solids: How theoretical prejudices influence its characterization. A critical review of analyses of experimental data
A. Mobius
In a recent experiment, Siegrist et al. [Nature Materials 10, 202 (2011)] investigated the metal-insulator transition (MIT) of GeSb_2Te_4 on increasing annealing temperature. The a…
Indications for a line of continuous phase transitions at finite temperatures connected with the apparent metal-insulator transition in 2d disordered systems
A. Mobius
In a recent experiment, Lai et al. [Phys. Rev. B 75 (2007) 033314] studied the apparent metal-insulator transition (MIT) of a Si quantum well structure. Tuning the charge carrier c…
Comment on "Density of States and Critical Behavior of the Coulomb Glass"
A. Mobius, M. Richter
In a recent numerical investigation of the Coulomb glass, Surer et al. [Phys. Rev. Lett. 102, 067205 (2009)] concluded that their simulation results are consistent with the Efros S…
Optimization by thermal cycling
A. Mobius, K. H. Hoffmann, C. Schon
Thermal cycling is an heuristic optimization algorithm which consists of cyclically heating and quenching by Metropolis and local search procedures, respectively, where the amplitu…
Specific heat of the Coulomb glass
A. Mobius, P. Thomas, J. Talamantes +1
The specific heat of the Coulomb glass is studied by numerical simulations. Both the lattice model with various strengths of disorder, and the random-position model are considered…
Non-ergodic effects in the Coulomb glass: specific heat
A. Díaz-Sánchez, A. Möbius, M. Ortuño +2
We present a numerical method for the investigation of non-ergodic effects in the Coulomb glass. For that, an almost complete set of low-energy many-particle states is obtained by…
Dielectric susceptibility of the Coulomb-glass
A. Diaz-Sanchez, M. Ortuno, M. Pollak +2
We derive a microscopic expression for the dielectric susceptibility of a Coulomb glass, which corresponds to the definition used in classical electrodynamics, the derivative o…
The metal-insulator transition in amorphous Si_{1-x}Ni_x: Evidence for Mott's minimum metallic conductivity
A. Mobius, C. Frenzel, R. Thielsch +10
We study the metal-insulator transition in two sets of amorphous Si_{1-x}Ni_x films. The sets were prepared by different, electron-beam-evaporation-based technologies: evaporation…
