WebWe present an analytic wave function describing a spin-singlet incompressible fluid of electrons confined to a single Landau level, which exhibits a half-integral quantum Hall effect. Our numerical studies suggest that this state may be responsible for the recently observed effect with \ensuremath{\nu}=(5/2. . AE Skip to Main Content Journals WebIn Chapter 7, we mentioned other quantum effects in the ordinary electrical resistance. The phenomenon described by (10.49), and known as the integral quantum Hall effect (QHE), earned Klaus von Klitzing the 1985 Nobel Prize in physics. efficiency apartments for rent arlington tx https://flowingrivermartialart.com

WebA review is given of recent experiments testing the two-parameter scaling theory of the integral quantum Hall effect. The temperature driven flow diagram in the σ XX (T) vs. σ xy (T) of the two-dimensional electrons in InGaAs-InP, measured from 10K to 50mk, shows scaling behavior and is consistent with the theory.
