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 ...

In a new study ( Nature Physics, "Orbital Seebeck effect induced by chiral phonons" ), researchers developed the most streamlined system yet for generating orbital angular momentum in electrons. Their ...

Phonons are the collective vibrations that move through a solid. They can be thought of as waves traveling across the atomic ...

Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable ...

A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

Researchers used sophisticated resonant X-ray scattering to directly view spin wave currents. The findings were published in Nature.

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 ...

(Nanowerk News) Micro mechanical elements are indispensable components of modern electrical devices but the actuation of them requires electrical current. It becomes harder to wire the element as ...

A quartz crystal subjected to a temperature gradient, leading to the generation of orbital angular momentum in the surrounding electron environment. To keep up with today’s computing needs, ...
