Erratum: Electrostatics revindicated classically

Classically Projective Groups and Pseudo Classically Closed Elds

The present variant is almost identical with the one from 1990. The main change is a correction in proof of Lemma 2.4, which was pointed out to me by Matthias Flach. I would also like to give my special thanks to P. Roquette and A. Prestel for several discussions we have had on this subject since the publication of the preprint. Finally, I would like to thank various people who showed interest ...

Classically Normal Pure States

A pure state f of a von Neumann algebra M is called classically normal if f is normal on any von Neumann subalgebra of M on which f is multiplicative. Assuming the continuum hypothesis, a separably represented von Neumann algebra M has classically normal, singular pure states iff there is a central projection p ∈ M such that pMp is a factor of type I∞, II, or III. DEFINITION: A pure state f of ...

Classically controlled quantum computation

It is reasonable to assume that quantum computations take place under the control of the classical world. For modeling this standard situation, we introduce a Classically-controlled Quantum Turing Machine (CQTM) which is a Turing machine with a quantum tape for acting on quantum data, and a classical transition function for a formalized classical control. In CQTM, unitary transformations and qu...

Electrostatics of nanowire transistors

S The electrostatics of nanowire transistors are studied by solving the Poisson equation self-consistently with the equilibrium carrier statistics of the nanowire. For a one-dimensional, intrinsic nanowire channel, charge transfer from the metal contacts is important. We examine how the charge transfer depends on the insulator and the metal/semiconductor Schottky barrier height. We also show th...
