Antimatter spectroscopy

First measurements of the line-shape of the 1s-2s in the antihydrogen atom are reported in a paper published in Nature, by the ALPHA collaboration, where Fysikum is a partner. The line shape agrees with ordinary hydrogen to a relative precision of 2x10-12, and thus puts an upper limit to the possible violation of matter-antimatter symmetries.

Giant ions precisely confined

The trapped ion quantum technologies group at Fysikum led by Markus Hennrich has published a paper in Physical Review X reporting the first Rydberg excitation of trapped strontium ions. Trapped Rydberg ions are a novel quantum system and a promising candidate for building a scalable quantum computer.
