Researchers at Technische Universität Darmstadt have recently demonstrated the defect-free assembly of versatile target patterns of up to 111 single-atom quantum systems. Their findings, outlined in a paper published in ...
Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
An active field of research, laser optical trapping works to control the movement and position of particles of different sizes and shapes. The ability to move small particles in a precise and controlled manner is important ...

(Phys.org)—Scientists have developed a method for imprinting tiny yet complex 3-D structures on the tip of an optical fiber, whose 125-µm diameter is roughly the thickness of a human hair. The 3-D optical structures can ...
(Phys.org)—Researchers have designed a nanoscale device that, under ideal conditions, can confine a "bit" of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically ...
(Phys.org) —Optical trapping, a technique for studying single molecules, is traditionally delicate, requiring special equipment and a soundproof room, with data collected one molecule at a time.
