Researchers have demonstrated that electron orbitals, not just spin, can serve as a practical lever for controlling magnetism in solid-state devices. A series of recent experiments and theoretical ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Phonons are the quantized lattice vibrations ...

The interplay between angular momentum, electron spin and magnetism at the nanoscale could have applications in spintronics, transducers and actuators, as well as fundamental research. In 1915, Albert ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has been ...

A new article describes the use of the Magnetorotational Instability Experiment to confirm an important mechanism involved in star formation. How have stars and planets developed from the clouds of ...
