Field Theoretic Description of Ultrarelativistic Electron-Positron Plasmas [PDF]

, 2008
Ultrarelativistic electron-positron plasmas can be produced in high-intensity laser fields and play a role in various astrophysical situations. Their properties can be calculated using QED at finite temperature.

On the Derivation of Vector Radiative Transfer Equation for Polarized Radiative Transport in Graded Index Media

, 2011
Light transport in graded index media follows a curved trajectory determined by the Fermat's principle. Besides the effect of variation of the refractive index on the transport of radiative intensity, the curved ray trajectory will induce geometrical ...

Quantitative Phase Imaging Camera With a Weak Diffuser

Frontiers in Physics, 2019
We introduce the quantitative phase imaging camera with a weak diffuser (QPICWD) as an effective scheme of quantitative phase imaging (QPI) based on normal microscope platforms.

Interplanetary particle transport simulation for warning system for aviation exposure to solar energetic particles

, 2015
Solar energetic particles (SEPs) are one of the extreme space weather phenomena. A huge SEP event increases the radiation dose received by aircrews, who should be warned of such events as early as possible.

Closed-Form Solution of Radial Transport of Tracers in Porous Media Influenced by Linear Drift

Energies, 2018
A new closed-form analytical solution to the radial transport of tracers in porous media under the influence of linear drift is presented. Specifically, the transport of tracers under convection–diffusion-dominated flow is considered.

Multiple scattering of light in superdiffusive media

, 2010
Light transport in superdiffusive media of finite size is studied theoretically. The intensity Green's function for a slab geometry is found by discretizing the fractional diffusion equation and employing the eigenfunction expansion method.
