Most precise determinations of fine structure in anti-hydrogen reported in this week's Nature

The most precise spectroscopic measurement of antimatter so far is reported in a paper published in Nature this week. The findings confirm the capabilities of anti-atom spectroscopy and bring the development of ultra-sensitive tests of antimatter one step closer.

Electrons in strong laser light get 'shaken up'

Danish publication Ingeniøren writes on 13 February 2018: Influenced by a very strong electromagnetic field electrons will experience a 'radiation reaction'; difficult to describe theoretically. Tobias Wistisen, Helge Knudsen and Ulrik Uggerhøj of IFA are co-authors in a recent paper in Nature Communications.
