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 ...

Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not ...

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 ...

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 ...

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 ...

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 ...
