Was Max-Planck-Physiker mit einem Atom machen, erinnert an manche Szene auf einem Spielplatz: Wie ein Vater seinem Kind auf einer Schaukel Schwung gibt, stoßen Forscher des Max-Planck-Instituts für Quantenoptik ein Atom an. Allerdings bremsen sie die Schwingungen des Atoms mit gezielten Schubsern, so als würde der Vater sein schaukelndes Kind mit sanften Stößen stoppen. Dafür nutzen die Wissenschaftler intensive Laserstrahlen, deren unzählige Photonen eine Kraft auf das Atom ausüben. Die Laser steuern sie mit einem sehr schnellen Rückkopplungsmechanismus, je nachdem wohin sich das Atom gerade bewegt. So halten sie das Atom bis zu 4 Mal länger in einem Resonator, den qmup xkpjjkgx izddceewuklefkkva Hetbswt pwsqzk, wju pako Ssawsuftduga.
