... (iv) K0 (Oq ) = Z. At least for the standard 1-parameter version of Oq , the fact that Oq is a domain can be proved in several other ways, but all of them seem to require considerably more knowledge about the structure of Oq . For example, for most values of the quantum parameter and for any classic ...

Enhancement of quantum dot peak-spacing fluctuations
... In this work we present calculations for an interacting electron system in a regime that can be treated almost exactly—the quantum Hall regime. The ground-state wave function in this regime is faithfully described by the Laughlin wave function [7]. Consequently, as long as the potential fluctuations ...

On the interpretation of measurement in quantum theory
... Such a dynamical decoupling of components is even more extreme if q~R and ~OL represent two states of a pointer corresponding t o different positions. Each state will now produce macroscopically correlated states: different images on the retina, different events in the brain, and different reactions ...
