Conceptual structure of total angular momentum manipulator: a light beam carrying multiple angular momentum modes passes through the manipulator for filtering. Credit: Li et al., doi ...

Rotating objects carry angular momentum; this fact extends even to the tiniest of particles, such as photons. Photons possess not one but two distinct forms of angular momentum: spin angular momentum ...

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 ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Subscribe to our newsletter for the latest ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

This article illustrates our group's most recent progress in developing an optimal path planner for rigid-body spacecraft rotations using Control Moment Gyroscopes (CMG's). This work improves upon our ...
