When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were ...

Every electron possesses two forms of angular momentum, Spin Angular Momentum (SAM) and Orbital Angular Momentum (OAM), with each having distinct characteristics. Spin Angular Momentum (SAM) is an ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

ABSTRACT: We analyzed the efficiency of a terahertz radiation produced at different pumping conditions of a first harmonic (ω0) Gaussian beam coupled with a second harmonic (2ω0) Laguerre-Gaussian ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

The mechanism of the color routing effect with the selective electron beam excitation at the nanoscale has been uncovered by Cheng Chi et al. from Beijing Engineering Research Center of Mixed Reality ...

In magnetic systems, angular momentum is carried by spin and orbital degrees of freedom. Nonlocal devices, comprising heavy-metal nanowires on magnetic insulators like yttrium iron garnet (YIG), ...

In this article, we will briefly discuss the history of who discovered the intrinsic angular momentum of the photon and present a heuristic derivation of the fact that the photon has spin one. Then, ...
