The AEgIS experimental program on antimatter systems involves the formation of antihydrogen atoms for gravitational and CPT studies. One of the key ingredients of the AEgIS strategy for the synthesis of antihydrogen atoms is the creation and manipulation of Positronium (Ps) atoms laser excited in Rydberg states ($n>15$).
Ps is very interesting in its own right. Ps is indeed a truly...

Positronium is an excellent test-bed for bound-state QED, owing to its purely leptonic nature. This allows its properties to be calculated very precisely in terms of the fine structure constant, with no contributions from hadronic interactions (weak interactions can also be neglected at the present experimental level). In addition to probing QED, a sufficiently precise measurement of the 1S-2S...

Recent advances in positron trapping techniques, positron to positronium
(Ps) converter materials, and commercially available pulsed laser
sources has greatly simplified the generation of Rydberg states of Ps.
Highly-excited states of this exotic atom are listed in several schemes
being developed for synthesis of anti-hydrogen for (anti)gravity
measurements. In contrast to its...
