International collaboration of physicists achieves first successful laser cooled Positronium, a short-lived atom significant for quantum studies

(G.N.S) Dt. 26 New Delhi, For the first time, an international collaboration of researchers has successfully demonstrated the laser cooling of Positronium, a short-lived hydrogen-like atom that provides an ideal testing ground for bound-state quantum electrodynamics. The Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy (AEgIS) collaboration has performed complex experiments at the European
