Researchers have demonstrated that electron orbitals, not just spin, can serve as a practical lever for controlling magnetism ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex ...

Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

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 ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Phonons are the quantized lattice vibrations ...

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 ...
