Energy, Particle, and Photon Fluxes in Molecular Junctions
The Journal of Physical Chemistry Letters, 2020Electroluminescence from a current-carrying molecular junction at steady state is simulated. (Charge) particle conservation and energy conservation are satisfied by a perturbative expansion in the radiation/matter coupling. Our approach makes it possible to adopt standard tools of traditional (equilibrium) spectroscopy to study signals from open ...

Heliospheric Energetic Particle Flux Variations
1999Energetic particles in the heliosphere represent a mixture of populations accelerated at the Sun, in various regions of the inner and outer heliosphere, and in galactic sources. Suprathermal and energetic particles usually play a minor role in the mass, momentum and energy density carried by the solar wind at 1 AU, although they are likely to have more

Contaminant Particles in Electronic Solder Fluxes
Soldering & Surface Mount Technology, 1990The filterable particles found in electronic solder fluxes vary considerably in both concentration and chemistry. Four fluxes from three manufacturers were examined, including both rosin fluxes and mildly activated resin fluxes. Individual particles were examined by optical light microscopy (OLM) and scanning electron microscopy/energy dispersive X‐ray

Erne observations of energetic particle fluxes
Advances in Space Research, 1997Abstract The observations of the ERNE instrument on-board the SOHO 1 spacecraft are analysed. The main period under study is from the beginning of May till mid-October 1996. Only very small energetic particle events were observed. A comparison of the ERNE measurements with energetic particle observations during the two previous solar minima ...

Inertial nonlinearity and chaotic motion of particle fluxes
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1993A brief review is given of the nonlinear phenomena arising in the evolution of random perturbations in particle fluxes of the hydrodynamical type, the velocity field of which is described by equations similar to the Riemann and Burgers equations. It is shown that a nonlinearity of the inertial type deforming the fluxes owing to the inertia of the ...

Measurement of magnetic fluctuation-induced particle flux (invited)
Review of Scientific Instruments, 2008Magnetic field fluctuation-induced particle transport has been directly measured in the high-temperature core of the MST reversed field pinch plasma. Measurement of radial particle transport is achieved by combining various interferometry techniques, including Faraday rotation, conventional interferometry, and differential interferometry.

Single-particle motion in a random magnetic flux
Physical Review B, 1993The motion of a quantum particle in a random magnetic flux in two dimensions is investigated. Two situations are distinguished, a ``Debye'' phase where the fluxes are uncorrelated, and a ``Meissner'' phase where the fluxes appear as neutral pairs. A geometrical interpretation of effective single-particle action in these phases is emphasized.

Heavy particle fluxes in Salyut space station orbit
Advances in Space Research, 1998Results of a detailed analysis of heavy ion fluences measured on the Salyut and MIR orbital stations from 1978 to 1990 are presented. The analysis has made use of new models that describe the cosmic ray fluxes and their transition through the magnetosphere.

Rapid variations of auroral particle fluxes
Journal of Geophysical Research, 1968Fast time resolution particle measurements on six French rockets flown into auroras at times near local midnight indicate that statistically significant intensity variations of electrons with energies from 65 to > 400 kev on time scales as short as several milliseconds often occur. Similar fluctuations of proton intensity are nearly absent.
