Magnetic, orbital and charge ordering in the electron-doped manganites
The three dimensional perovskite manganites R1−xAxMnO3 in the range of holedoping x > 0.5 are studied in detail using a double exchange model with degenerate eg orbitals including intraand inter-orbital correlations and near-neighbour Coulomb repulsion. We show that such a model captures the observed phase diagram and orbital-ordering in the intermediate to large band-width regime. It is argued...
متن کاملOrbital ordering phenomena in d- and f-electron systems
In recent decades, novel magnetism of dand f -electron compounds has been discussed very intensively both in experimental and theoretical research fields of condensed matter physics. It has been recognized that those material groups are in the same category of strongly correlated electron systems, while the low-energy physics of dand f -electron compounds has been separately investigated rather...
متن کاملElectron-Phonon and Electron-Electron Interactions in Quantum Transport
The objective of this work is t o shed light on electron transport through sub-micron semiconductor structures, where electronic state quantization, electron-electron interactions and electron-phonon interactions are important. We concentrate here on the most developed vertical quantum device, the double barrier resonant tunneling diode. In this work we analyze particle interactions in two stru...
متن کاملElectron-electron interactions in graphene bilayers
We study the effect of electron-electron interactions in the quasiparticle dispersion of a graphene bilayer within the Hartree-Fock-Thomas-Fermi theory by using a four-bands model. We find that the electronic fluid can be described by a non-interacting like dispersion but with renormalized parameters. We compare our results with recent cyclotron resonance experiments in this system. Since graph...
متن کاملAccurate Three-Dimensional Simulation of Electron Mobility Including Electron-Electron and Electron-Dopant Interactions
The continuous scaling of MOSFET devices into the nanoscale regime requires refined models for electron transport. Coulomb interactions must be considered because of two reasons. First the Coulomb force is a long range force implying that both the short and the long range interactions must be included in a particle ensemble. Second the hot-carrier and short-channel effects will have a significa...
