We report on numerical studies of the influence of Coulomb interactions on the localization of electronic wave functions in a strong magnetic field. Interactions are treated in the Hartree-Fock approximation. Localization properties are studied both by evaluating participation ratios of Hartree-Fock eigenfunctions and by studying the boundary-condition dependence of Hartree-Fock eigenvalues. We find that interactions have no effect on the critical exponent characterizing the diverging… 
Interactions in the integer quantum Hall effect: Critical conductivity and dynamical scaling
Abstract We investigate numerically the influence of Coulomb interactions on the critical properties of the integer quantum Hall system in the lowest Landau level. Disorder is treated exactly while
Hartree-Fock interactions in the integer quantum Hall effect
We report on numerical studies into the interplay of disorder and electron-electron interactions within the integer quantum Hall regime, where the presence of a strong magnetic field and
Electron correlations and single-particle physics in the integer quantum Hall effect.
TLDR
The compressibility of a two-dimensional electron system with spin in a spatially correlated random potential and a quantizing magnetic field is investigated and localization-delocalization transitions associated with a highly compressible region in the energy spectrum are found at half-integer filling factors.
Scaling theory of the integer quantum Hall effect
A brief review is given of the present understanding of the transitions between integer quantized plateaus of the Hall conductivity in two-dimensional disordered systems in a strong magnetic field.
DC- and AC-scaling of the integer quantum Hall effect in the presence of interactions
The temperature and frequency dependence of the plateau-to-plateau transitions in the quantum Hall effect are investigated experimentally for up to 5 Landau bands. Features induced by Coulomb
Integer quantum Hall effect in a lattice model revisited: Kubo formalism
We investigate numerically the integer quantum Hall effect (IQHE) in a two-dimensional square lattice with non-interacting electrons in presence of disorder and subjected to uniform magnetic field in
Dynamics of electronic transport in the integer quantum Hall regime
We examine different aspects of the dynamics of electronic transport in the integer quantum Hall effect. In the first part the quantum Hall plateau transition is studied. We present experimental
Non-Fermi-liquid theory for disordered metals near two dimensions
We consider the Finkelstein action describing a system of spin-polarized or spinless electrons in 2+2epsilon dimensions, in the presence of disorder as well as the Coulomb interactions. We extend the
Scaling in the Integer Quantum Hall Effect: interactions and low magnetic fields
Recent developments in the scaling theory of the integer quantum Hall effect are discussed. In particular, the influence of electron-electron interactions on the critical behavior is studied. It is
Compressibility in the integer Quantum Hall Effect within Hartree-Fock approximation
Electron-electron interactions seem to play a surprisingly small role in the description of the integer quantum Hall effect, considering that for just slightly different filling factors the
