How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

Abstract: In this article, we propose a method based on the aperture antennas theory to understand the limitations of orbital angular momentum (OAM) antennas in far-field links. Additional insight is ...

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the ...

Video from the U.S. Geological Survey showed Kilauea volcano spewing lava more than 800 feet into the air in its latest eruption on Hawaii's Big Island. USGS said the eruption began around 4:15 p.m.

A new experiment encodes quantum information in the motion of the atoms and creates a state known as hyper-entanglement, in which two or more traits are linked among a pair of atoms.

ABSTRACT: A parametrization of density matrices of d dimensions in terms of the raising J + and lowering J − angular momentum operators is established together with an implicit connection with the ...

The metal-d- or metalf-based orbitals are canonicalized by diagonalizing the matrix representation of the angular momentum operator L ^ z and then phase-adjusted to be consistent with the ligand field ...

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 this work, we have derived a generalized form of the gluon orbital angular momentum operator at small-x for a longitudinally polarized proton. This expression reproduces the gluon OAM operator ...

A thorough discussion of this topic reinforces important concepts such as spin-orbit coupling interaction, the Zeeman effect, and the fundamental role that different sources of angular momentum play .

Sennheiser's Momentum True Wireless 4 have class-leading audio handling and boost sound quality to rival the best wireless earbuds, but this next-gen version adds significantly to the price.
