It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

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 ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Optical holography is a powerful method for recording and reconstructing complete optical field information, including intensity and phase. It has found extensive applications in various fields, such ...

The article explores how the Big Bang initiated the universe's continuous motion, affecting vast cosmic distances through expansion. Angular momentum drives local rotations, while dark matter ...

Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Subscribe to our newsletter for the latest ...

Hybrid continuous-variable (CV) and discrete-variable (DV) entanglement is an essential quantum resource of hybrid quantum information processing, which enables one to overcome the intrinsic ...
