A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

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 ...

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.

Researchers have developed an optical "knob" using Poincaré sphere engineering to continuously tune topological states in ...
