Physics and the measurement of continuous variables

R. N. Sen

Wigner had expressed the opinion that the impossibility of exact measurements of single operators like position operators rendered the notion of geometrical points somewhat dubious…

Noise from metallic surfaces -- effects of charge diffusion

Carsten Henkel, Baruch Horovitz

Non-local electrodynamic models are developed for describing metallic surfaces for a diffusive metal. The electric field noise at a distance z_0 from the surface is evaluated and c…

NMR method for amplification of single spin state

Gregory B. Furman, Victor M. Meerovich, Vladimir L. Sokolovsky

Amplification of a single spin state using nuclear magnetic resonance (NMR) techniques in a rotating frame is considered. The main aim is to investigate the efficient of various sc…

Classical limit of the Casimir entropy for scalar massless field

S. Rubin, J. Feinberg, A. Mann +1

We study the Casimir effect at finite temperature for a massless scalar field in the parallel plates geometry in N spatial dimensions, under various combinations of Dirichlet and N…

Counting statistics in multiple path geometries and the fluctuations of the integrated current in a quantum stirring device

Maya Chuchem, Doron Cohen

The amount of particles that are transported via a path of motion is characterized by its expectation value and by its variance . We analyze what happens if a par…
