Electron-atom bremsstrahlung: double differential cross section and polarization correlations
Electron-atom bremsstrahlung double differential cross section polarization correlations
2010/11/16
The leading-order electron-atom bremsstrahlung is investigated within the rigorous relativistic approach based on the partial-wave representation of the Dirac wave functions in the external atomic fi...
An accelerated particle sees the Minkowski vacuum as thermally excited, and the particle
moves stochastically due to an interaction with the thermal bath. This interaction fluctuates
the particle’s ...
On a possibility of effective electron attraction without "a glue"
possibility of effective electron attraction
2010/11/25
Despite being under attack for almost twenty-five years there is no yet a commonly accepted solution for the problem of high temperature superconductivity1. Among different approaches there are theore...

The electromagnetic properties of the deuteron are investigated within a Light-Front Hamilto-
nian Dynamics framework, with a current operator that contains both one-body and two-body
contributions....

2010/11/22
The focusing of electron flow in a symmetric p-n junction (PNJ) of graphene ribbon with different chiralities is studied. Considering the PNJ with the sharp interface, in a armchair ribbon, the electr...
Rare-gas clusters in intense VUV, XUV and soft x-ray pulses: Signatures of the transition from nanoplasma-driven cluster expansion to Coulomb explosion in ion and electron spectra
VUV XUV soft x-ray pulses
2010/11/16
We investigate the wavelength dependent ionization, heating, and expansion dynamics of medium-sized rare-gas clusters (Ar$_{923}$) under intense femtosecond short-wavelength free electron laser pulse...

Graphane Nanoribbon Superlattice
2010/11/23
Nearly free electron (NFE) state has been widely studied in low dimensional systems. Based on
first-principles calculations, we identify two types of NFE states in graphane nanoribbon
superlattice, ...
