Local Electric Field Variation in the Field Emission Process
"... Abstract: Tunnelling probabilities in field emission processes are usually calculated assuming flat emitting surfaces. This corresponds to consider the electric field as a constant along the potential barrier. Previous work have shown the importance of taking into account image effects but neglectin ..."

LOCAL ELECTRIC FIELD MEASUREMENTS BY OPTICAL TWEEZERS
"... ABSTRACT. We report a new technique to measure direction and amplitude of electric fields generated by microelectrodes embedded in polar liquid environment, as often used in microfluidic devices. The method is based on optical tweezers which act as sensitive force transducer while a trapped charged ..."

Imaging local electric fields produced upon synchrotron X-ray exposure
"... Electron-hole separation following hard X-ray absorption during diffraction analysis of soft materials under cryogenic conditions produces substantial local electric fields visualizable by second harmonic generation (SHG) microscopy. Monte Carlo simulations of X-ray photoelectron trajectories sugge ..."

Permittivity and its temperature dependence in hexagonal structure BN dominated by the local electric field *
, 2012
"... This paper presents an analysis of the local electric field in hexagonal boron nitride (h-BN) by introducing a modified parameter. Based on the determination of the modified parameter of h-BN, the revised Lorenz equation is developed. Then the permittivity at high temperature and in the microwave f ..."

Macroscopic strings as heavy quarks in large N gauge theory and Anti-de Sitter supergravity
- PHYS. J. C22
"... Maldacena has put forward large N correspondence between superconformal field theories on the brane and anti-de Sitter supergravity in spacetime. We study some aspects of the correspondence between N = 4 superconformal gauge theory on D3-brane and maximal supergravity on adS5 × S5 by introducing mac ..."

Spectral analysis of cytochrome c: effect of heme conformation, axial ligand, peripheral substituents and local electric fields,
- J. Phys. Chem. B
, 2001
"... We present in this work low-temperature visible absorption spectra for recombinant Thermus thermophilus cytochrome c 552 . The Q-band presents a remarkable splitting at low temperature. We performed quantum chemical calculations to evaluate quantitatively the effect of heme conformation, axial liga ..."

ligand, peripheral substituents and local electric fields on the electronic spectra. In an attempt to find correlation between protein structure and spectral splitting, we carried out the same calculations on three other cytochrome c's: horse heart, tuna heart, and yeast. The quantum chemical
Axiomatic quantum field theory in curved spacetime
, 2008
"... The usual formulations of quantum field theory in Minkowski spacetime make crucial use of features—such as Poincare invariance and the existence of a preferred vacuum state—that are very special to Minkowski spacetime. In order to generalize the formulation of quantum field theory to arbitrary globa ..."

globally hyperbolic curved spacetimes, it is essential that the theory be formulated in an entirely local and covariant manner, without assuming the presence of a preferred state. We propose a new framework for quantum field theory, in which the existence of an Operator Product Expansion (OPE) is elevated
DiamondTouch: a multi-user touch technology
, 2003
"... A technique for creating touch sensitive surfaces is proposed which allows multiple, simultaneous users to interact in an intuitive fashion. Touch location information is determined independently for each user, allowing each touch on the common surface to be associated with a particular user. The su ..."

We describe the design of these sytems and their applications. Finally, we conclude with a description of the results we have obtained with a first
