Recently, physicists at Universität Hamburg demonstrated in a theoretical work that superfluidity emerges, when the atoms of a cold quantum gas are shaken by shining light on them. Now the scientists, who are also members of CUI, could experimentally proof the predictions. Their findings clearify a controversal debate on experimental observations of a light-induced increase in the transition temperature of electronic superconductors.
