Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai ...

New spin on topology: spin guided light scattering has been observed in a liquid crystal (Courtesy: Shutterstock/Serg-DAV) Just as topological insulators provide protection to electrons travelling ...

Quantum technologies, devices that work by leveraging quantum mechanical effects, could outperform classical technologies in some fields and settings. The so-called spin (i.e., intrinsic angular ...

(Nanowerk News) Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown (Science Advances, "Field ...

Rotating objects carry angular momentum; this fact extends even to the tiniest of particles, such as photons. Photons possess not one but two distinct forms of angular momentum: spin angular momentum ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

A team of Harvard physicists published an article Wednesday outlining a novel method for determining the “spin” — or angular momentum — of a black hole. The paper appeared in Physical Review D, a peer ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
