Efficient numerical simulation of atmospheric pulsed discharges by introducing deep learning

open access: yesFrontiers in Physics, 2023
Plasma simulation is an important but sometimes time-consuming approach to study the discharge behaviors of atmospheric pulsed discharges. In this work, an efficient simulation method is proposed by introducing deep learning to investigate the discharge ...

Search for Matter-Dependent Atmospheric Neutrino Oscillations in Super-Kamiokande [PDF]

open access: yes, 2008
We consider muon neutrino to tau neutrino oscillations in the context of the Mass Varying Neutrino (MaVaN) model, where the neutrino mass can vary depending on the electron density along the flight path of the neutrino.

Tracing electron density changes in langbeinite under pressure

open access: yesIUCrJ, 2022
Pressure is well known to dramatically alter physical properties and chemical behaviour of materials, much of which is due to the changes in chemical bonding that accompany compression.

Mid-point electron density profiles from oblique ionograms

open access: yesAnnals of Geophysics, 1996
A computationally efficient technique for the inversion of oblique ionograms into mid-point electron density profiles is described. The profile is given as the sum of quasi-parabolic functions suitable for ray tracing.

THE EFFECTS OF SOLAR ACTIVITY: ELECTRONS IN THE TERRESTRIAL LOWER IONOSPHERE [PDF]

open access: yesZbornik Radova: Geografski institut "Jovan Cvijić", 2017
Solar flare X-ray energy can cause strong enhancements of the electron density in the Earth’s atmosphere. This intense solar radiation and activity can cause sudden ionospheric disturbances (SIDs) and further create ground telecommunication interferences,

Intermittent electron density and temperature fluctuations and associated fluxes in the Alcator C-Mod scrape-off layer [PDF]

open access: yes, 2018
The Alcator C-Mod mirror Langmuir probe system has been used to sample data time series of fluctuating plasma parameters in the outboard mid-plane far scrape-off layer. We present a statistical analysis of one second long time series of electron density,

Scaling relations, virial theorem and energy densities for long-range and short-range density functionals [PDF]

open access: yes, 2006
We analyze a decomposition of the Coulomb electron-electron interaction into a long-range and a short-range part in the framework of density functional theory, deriving some scaling relations and the corresponding virial theorem. We study the behavior of

Properties of short-range and long-range correlation energy density functionals from electron-electron coalescence [PDF]

open access: yes, 2006
The combination of density functional theory with other approaches to the many-electron problem through the separation of the electron-electron interaction into a short-range and a long-range contribution is a promising method, which is raising more and ...

An effective potential of electron-electron interaction in semi-infinite jellium

open access: yesCondensed Matter Physics, 2006
An effective potential of electron-electron interaction and a two-particle "density-density" correlator are calculated for semi-infinite jellium. Their asymptotics at large distances between electrons are studied in a plane parallel to the surface.
