Electromagnetic momentum and optical forces have emerged as pivotal concepts in modern optical science, bridging fundamental physics and advanced technological applications. At its core, ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

Light is not only an important carrier of information but also a carrier of energy. When light interacts with matter, it can induce subtle mechanical effects, known as optical forces. This non-contact ...

A tiny, first-of-its-kind, nanoscale demonstration shows how we could one day send a spacecraft to another star, within a ...

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

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk Institute of Science and Technology (DGIST), has successfully developed an ...

New York, NY—January 1, 2025—Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution ...
