. In his work on collective oscillations and pairing energies, Grimm found first evidence of the flow of particles without any loss of energy (superfluidity) in Fermi condensates. Meanwhile Grimm and his team have succeeded in producing more complex molecules in ultracold quantum gases. Currently Grimm is concentrating his efforts on producing mixed condensation from atoms of different elements. In 2006, his working group also managed to lift the veil on an old mystery of physics: they succeeded in the first experimental observation of Efimov State
Efimov State
The Efimov effect is an effect in the quantum mechanics of Few-body systems predicted by the Soviet theoretical physicist V. N. Efimov in 1970. Efimov’s effect refers to a scenario in which three identical bosons interact, with the prediction of an infinite series of excited three-body energy...
