PRA Kaleidoscopes: two good looking electrons

Last updated May 30, 2017 by Andrew Brown

Two-electron Probability Distribution

An image from a recent publication by CTAMOP researchers has been selected by Physical Review A for their ‘Kaleidoscopes’ collection.

The image is taken from ” Double ionization in R-matrix theory using a two-electron outer region”by Jack Wragg, Jonathan Parker and Hugo van der Hart.

It shows the two-electron probability distribution for helium after interaction with a soft x-ray laser pulse, and demonstrates the new capability to describe two-electron processes being developed by the researchers.

While the website notes that the image is chosen for its aesthetic quality, the science it represents is a significant step forward for computational physics. Congratulations to Jack, Jonathan and Hugo for their achievement.
