Two-Dimensional Electrons in a Strong Magnetic Field with Disorder: Divergence of the Localization Length
Electrons on a square lattice with half a flux quantum per plaquette are considered. An effective description for the current loops is given by a twodimensional Dirac theory with random mass. It is shown that the conductivity and the localization length can be calculated from a product of Dirac Green’s functions with the same frequency. This implies that the delocalization of electrons in a mag...
متن کاملLocalization of charged quantum particles in a static random magnetic field.
We consider a charged quantum particle in a random magnetic field with Gaussian, delta-correlated statistics. We show that although the single particle properties are peculiar, two particle quantities such as the diffusion constant can be calculated in perturbation theory. We map the problem onto a non-linear sigma-model for Q-matrices of unitary symmetry with renormal-ized diffusion coefficien...
متن کاملMagnetic-field-induced localization transition in HgCdTe.
We have performed magnetoresistance and Hall-resistance measurements on low —carrierconcentration n-type samples of Hg076Cdp24Te at millikelvin temperatures. We observe an abrupt rise in the Hall resistance and magnetoresistance at a characteristic field H, which is a significant function of temperature and which allows us to reject magnetic freezeout or localization by disorder as possible mec...
متن کاملSolution of the Boltzmann equation in a random magnetic field.
A general framework for solving the Boltzmann equation for a 2-dimensional electron gas (2DEG) in random magnetic fields is presented, when the random fields are included in the driving force. The formalism is applied to some recent experiments, and a possible extension to composite fermions at ν = 1/2 is discussed.
متن کاملMagnetoresistance of Two-Dimensional Fermions in a Random Magnetic Field.
We perform a semiclassical calculation of the magnetoresistance of spinless two-dimensional fermions in a long-range correlated random magnetic field. In the regime relevant for the problem of the half filled Landau level the perturbative Born approximation fails and we develop a new method of solving the Boltzmann equation beyond the relaxation time approximation. In absence of interactions, e...
