Physicists at Purdue University have achieved a significant breakthrough by creating a unique experimental setup involving levitated fluorescent nanodiamonds. These tiny diamonds are not just floating in a vacuum; they’re spinning at incredibly high speeds, emitting and scattering multicolored lights as they rotate. This research, led by Tongcang Li, a professor at Purdue, marks an exciting advancement in the study of rotating quantum systems and levitodynamics, with their results published in Nature Communications. Reviewers have hailed the work as “arguably a groundbreaking moment” and “a ne…
