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

The study of structured optical waves has enhanced our understanding of light and numerous experimental methods now enable the control of the angular momentum and radial distributions. Recently, these ...

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

This paper is concerned chiefly with the introduction of a co-ordinate operator in the quantum mechanics of the electron. It differs from other work on the same subject in the derivation of the form ...

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 ...

In a new study ( Nature Physics, "Orbital Seebeck effect induced by chiral phonons" ), researchers developed the most ...

Photons with a twisted phase front carry a quantized amount of orbital angular momentum (OAM) and have become important in various fields of optics, such as quantum and classical information science ...

Scientists experimentally confirm electron vortices in momentum space, a quantum phenomenon that could enable efficient, low-energy quantum technologies. (Nanowerk News) A breakthrough that’s turning ...

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 ...

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