When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...
Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

Physicists patch a major hole in a key quantum theorem
Physicists have long relied on elegant theorems to connect the abstract math of quantum theory with the tangible behavior of ...
Unlock the mysteries of rolling motion, torque, and angular momentum in Chapter 11! Learn how rotational motion works and how it differs from linear motion. #RollingMotion #Torque #AngularMomentum #Ph ...
Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not ...
Optical vortices are currently one of the most intensively studied topics in optics. These light beams, which carry orbital angular momentum (OAM), have been successfully utilized in the visible and ...
Angular momentum is the rotational version of linear momentum; conservation of angular momentum is the rotational version of Newton’s law of conservation of linear momentum. Conservation of angular ...
Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
