In collaboration with the research group of Osaka University, Professor Emeritus Hiroshi Fukuyama (Professor at the time) and Professor Kensuke Kobayashi discovered a phenomenon in which the resistance became negative near zero current despite the superconducting state by adding an external vibration field in the GHz band called surface acoustic waves(SAWs) to atomically thin superconductor NbSe2 crystallites.

The results of this research were published in the American science journal "Science Advances " at on August 21, 2020.
