New record set for coldest temperature—38 picokelvins

A team of researchers affiliated with several institutions in Germany and two in France has set a new record for the coldest temperature ever recorded in a lab setting—38 picokelvins. In their paper published in the journal Physics, the group describes their work with a time-domain matter-wave lens system. Vincenzo Tamma with the University of Portsmouth has published a Viewpoint article in the same journal issue discussing the work done by the team in Germany.
