Super-transition-array calculations for synthetic spectra and opacity of high-density, high-temperature germanium plasmas [PDF]

open access: yes, 2020
The synthetic emission spectra and opacity of high-density, high-temperature germanium (Z=32) plasma from super-transition-array (STA) calculations are presented. The viability of the STA model, which is based on a statistical superconfigurations accounting approach for calculating the atomic and radiative properties, is examined by comparing and ...

Ablation of Submicrometer Holes Using an Extreme-Ultraviolet Laser [PDF]

open access: yes, 2015
Simulations and experiments are used to study extreme-ultraviolet (EUV) laser drilling of submicrometer holes. The ablation process is studied with a 2D Eulerian hydrodynamic code that includes bound-free absorption processes relevant to the interaction ...

A consistent approach for mixed detailed and statistical calculation of opacities in hot plasmas

open access: yes, 2011
Absorption and emission spectra of plasmas with multicharged-ions contain transition arrays with a huge number of coalescent electric-dipole (E1) lines, which are well suited for treatment by the unresolved transition array and derivative methods.

A Configurationally-Resolved-Super-Transition-Arrays method for calculation of the spectral absorption coefficient in hot plasmas

open access: yes, 2012
A new method, 'Configurationally-Resolved-Super-Transition-Arrays', for calculation of the spectral absorption coefficient in hot plasmas is presented. In the new method, the spectrum of each Super-Transition-Array is evaluated as the Fourier transform ...

A variational atomic model of plasma accounting for ion radial correlations and electronic structure of ions (VAMPIRES)

open access: yes, 2022
We propose a model of ion-electron plasma (or nucleus-electron plasma) that accounts for the electronic structure around nuclei (i.e. ion structure) as well as for ion-ion correlations.

Requirements for the workflow-based support of release management processes in the automotive sector [PDF]

open access: yes, 2005
One of the challenges the automotive industry currently has to master is the complexity of the electrical/elctronic system of a car. One key factor for reaching short product development cycles and high quality in this area are well-defined, properly ...

Jensen-Feynman approach to the statistics of interacting electrons

open access: yes, 2009
Faussurier et al. [Phys. Rev. E 65, 016403 (2001)] proposed to use a variational principle relying on Jensen-Feynman (or Gibbs-Bogoliubov) inequality in order to optimize the accounting for two-particle interactions in the calculation of canonical ...
