An international team of scientists led by Dr. Lukas Bruder, junior research group leader at the Institute of Physics, University of Freiburg, has succeeded in producing and directly controlling hybrid electron-photon quantum states in helium atoms.
To this end, they generated specially prepared, highly intense extreme ultraviolet light pulses using the FERMI free electron laser in Trieste, Italy. The researchers achieved control of the hybrid quantum states using a new laser pulse-shaping technique. Their results have been published in the journal Nature.
