http://large.stanford.edu/publications/ WebA century later, the Hall effect was revived as a source of astonishing new physics. In 1980 at the Grenoble High Magnetic Field Laboratory in France, Klaus von Klitzing was studying the Hall conductance of a two-dimensional electron gas at very low temperatures. He discovered, in essence, that the Hall conductance, as a function of the strength of the … WebAbstract. Dynamics of two dimensional electrons under the strong perpendicular magnetic field is shown to be described by a multi-component fermion theory. The electric conductance has a remarkable property known as the quantum Hall effect.

WebDec 20, 1995 · The invariance of these features from the classical- to the quantum–limits suggest that the bulk current is maintained under steady-state quantized Hall effect (QHE) conditions, while the observation of dual simultaneous quantum Hall plateaus provides a new perspective into aspects of the `gauge argument' thought experiment (R. B. Laughlin: … WebAbstract. The dc conductance Γ of a finite system with static disorder is related to its transmission matrix t by the simple relation Γ = ( e2 2πℏ) Tr(t†t). This relation is derived from the Kubo formula and is valid for any number of scattering channels with or without time-reversal symmetry. Differences between various definitions of ...
