Scientists from the Graduate School of Engineering Science at Osaka University used optical tweezers for the first time inside superfluid helium. With a strongly focused beam of light, they demonstrated the stable trapping of nanoparticles at ultralow temperatures. This work may help scientists better understand the conceptual boundary that separates classical and quantum effects.
