Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Although this seems like a simple expression, there is much to go over. First, the L vector represents the angular momentum—yes, it's a vector. Second, the r vector is a distance vector from ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy ...

In this letter, we report on experimental evidence for such a quantum Einstein-de Haas effect and demonstrate that conservation of total angular momentum and energy fully suppresses QTM in a SMM ...

The more degrees of freedom a quantum observable has, the more complicated it is to measure its probability distribution. Here, the authors deduce the mean and variance of an infinite-dimensional ...
