= Angular momentum operator
{wiki=Angular_momentum_operator}
In quantum mechanics, the angular momentum operator is an important operator that describes the angular momentum of a quantum system, similar to how the linear momentum operator describes the linear momentum. Angular momentum is a key concept in both classical and quantum physics, and it plays a crucial role in the behavior of atomic and subatomic particles. There are several forms of angular momentum in quantum mechanics, including orbital angular momentum and spin angular momentum.
