Often, when planets form in a protoplanetary disk, they shed orbital angular momentum, exchanging this angular momentum with the disk that they are accreting material from in order to grow.

The phenomenon of the conservation of angular momentum caused the material ... interactions within the protoplanetary disk led to orbital migrations with planets moving inward or outward.

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 ...

A similar interference effect also appears in a closely related property of light known as orbital angular momentum, which allows light to rotate particles around the optical axis, i.e., make them ...
