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 ...

A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

Here, quantum states are prepared with unequal distribution of uncertainty between conjugate observables, in this case, the projections of the angular momentum ... is the rotation angle φ of ...

This expansion is most noticeable on the largest cosmic scales. Angular momentum is crucial to cosmic rotation. When two objects in space come close together, their mutual gravity pulls them ...

“Climate change is causing the Earth’s axis of rotation to move, and it appears that the feedback from the conservation of angular momentum is also changing the dynamics of the Earth’s core ...

Quantum entanglements between integer-order and fractional-order orbital angular momentums (OAMs) have been previously discussed. However, the entangled nature of arbitrary rational-order OAM has ...
