Peak Values of Conductivity in Integer and Fractional Quantum Hall Effect
نویسنده
چکیده
The diagonal conductivity usr was measured in the Corbino geometry in both integer and fractional quantum Hall effect (QHE). We find that peak values of g=.+ are approximately equal for transitions in a wide range of integer filling factors 3 < v < 16, as expected in scaling theories of QHE. This fact allows us to compare peak values in the integer and fractional regimes within the framework of the law of corresponding states.

Duality and the Modular Group in the Quantum Hall Effect
We explore the consequences of introducing a complex conductivity into the quantum Hall effect. This leads naturally to an action of the modular group on the upper-half complex conductivity plane. Assuming that the action of a certain subgroup, compatible with the law of corresponding states, commutes with the renormalisation group flow, we derive many properties of both the integer and fractio...
متن کاملTowards the Fractional Quantum Hall Effect: a Noncommutative Geometry Perspective
In this paper we give a survey of some models of the integer and fractional quantum Hall effect based on noncommutative geometry. We begin by recalling some classical geometry of electrons in solids and the passage to noncommutative geometry produced by the presence of a magnetic field. We recall how one can obtain this way a single electron model of the integer quantum Hall effect. While in th...

متن کاملDynamical critical behavior in the integer quantum Hall effect
We investigate dynamical scaling properties in the integer quantum Hall effect for non-interacting electrons at zero temperature, by means of the frequency-induced peak broadening of the dissipative longitudinal conductivity σ xx (ω). This quantity is calculated numerically in the lowest Landau level for various values of the Fermi energy E, of the frequency ω, and of the system size L. Data fo...

We discuss a model for the integer quantum Hall effect which is based on a Schroedinger-Chern-Simons-action functional for a non-interacting system of electrons in an electromagnetic field on a mutiply connected manifold. In this model the integer values of the Hall conductivity arises in view of the quanti-zation of the Chern-Simons-action functional for electromagnetic potential.
