Quantum Hall effect at finite temperatures.
The underlying physics of the quantum Hall effect (QHE) is understood in terms of the Anderson localization in two dimensions (2D): a weakly disordered 2D electron gas experiences a series of metal-insulator transitions with increasing magnetic field B. The field-induced transitions are degenerate in the sense that the metallic phase occurs only at some particular values of B. At zero temperatu...

متن کاملNovel Finite Temperature Conductivity in Quantum Hall Systems
We study quantum Hall systems (mainly the integer case) at finite temperatures and show that there is a novel temperature dependence even for a pure system, thanks to the ‘anomalous’ nature of generators of translation. The deviation of Hall conductivity from its zero temperature value is controlled by a parameter T0 = πρ/m N which is sample specific and hence the universality of quantization i...
متن کاملOptical Conductivity of Clean Metals
We briefly review some basic aspects of transport in clean metals focusing on the role of electron-electron interactions and neglecting the effects of impurities, phonons and interband transitions. Both for small Fermi surfaces of two and three-dimensional metals and open Fermi surfaces of quasi one-dimensional metals the dc conductivity σ is largely dominated by momentum and pseudo-momentum co...
متن کاملAnomalous Hall effect
We present a review of experimental and theoretical studies of the anomalous Hall effect (AHE), focusing on recent developments that have provided a more complete framework for understanding this subtle phenomenon and have, in many instances, replaced controversy by clarity. Synergy between experimental and theoretical work, both playing a crucial role, has been at the heart of these advances. ...
