Although elusive, the quantum spin has led to some of the deepest insights we now know. Quantum mechanics has a lot of weird stuff - but there are things that everyone agrees that no one understands.

Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have ...

Fundamental properties of the planet Venus, such as its internal mass distribution and variations in length of day, have remained unknown. We used Earth-based observations of radar speckles tied to ...

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 ...

Conventional electronic devices rely on the generation, transport, manipulation, and detection of electric charge carriers, such as electrons and holes. Spintronics employs the intrinsic angular ...

Acoustic waves are usually thought of as purely longitudinal, moving back and forth in the direction the wave is travelling and having no intrinsic rotation, therefore no spin (spin‑0). Recent work ...

When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...
