Coulomb Effects on the Magnetoconductance of a Two-Dimensional Electron Gas in a Lateral Superlattice: A Screened Hartree-Fock Calculation
Andrei Manolescu, Rolf R. Gerhardts
We calculate the magnetoconductivity tensor of a 2D electron gas in a 1D periodic potential and quantising magnetic fields. We study the internal structure of the Shubnikov-de Haas…

Is the Hofstadter energy spectrum observable in far-infrared absorption?
Vidar Gudmundsson, Rolf R. Gerhardts
The far-infrared absorption of a periodically modulated two-dimensional electron gas in a perpendicular constant magnetic field is calculated self-consistently within the Hartree a…
