Physicists in Australia have become the first researchers to levitate a macroscopic object using lasers. The physicists used three lasers to form a levitational "tripod" that could hold a small mirror ...

(Nanowerk News) Researchers have created tiny chip-based optical tweezers that can be used to optically levitate nanoparticles in a vacuum. Optical tweezers — which employ a tightly focused laser beam ...

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional ...

Scientists have taken a cutting-edge development from 2018 and pushed it even further, creating a levitation ray capable of lifting microscopic material. At the heart of this innovation is a ...

Schematic of optically levitating a nanoparticle with a metalens in a vacuum. The metalens focuses a laser beam to create chip-based optical tweezers. Disclaimer: AAAS and EurekAlert! are not ...

Researchers report the first realization of on-chip optical levitation in a vacuum with an ultrathin metalens. Accomplishing this feat in a vacuum helps improve the sensitivity of the system.
