Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

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 ...

Orbital angular momentum (OAM) presents a promising degree of freedom for enhancing data transmission in optical communications. By utilising the helical phase front of light beams, OAM offers a ...

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 ...

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting ...
