Researchers at the University of British Columbia, RIKEN, and Kanazawa University created nano-size, ultra-cold labs to demonstrate superfluidity in hydrogen. Credit: Dr. Susumu Kuma, RIKEN Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium. The new research is published in Science Advances by an international team led by chemists at the University of British Columbia (UBC). "This discovery deepens our unders...
