Michael Knap's group at the Technical University of Munich (TUM) and scientistists from Harvard University in the USA proposed to apply the methods used in extremely accurate atomic clocks to create an ultra-cold environment in which the formation of quasiparticles takes place in slow-motion. Under these conditions, the group led by Rudolf Grimm at the Institute of Experimental Physics of the University of Innsbruck and the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences succeeded in producing precisely controllable many-particle systems. This made it possible, for the first time ever, to study the creation of quasiparticles in real time. For further information, look also at the TUM Press Release .
