Fundamental Commutation Relations in Quantum Mechanics
Fundamental Commutation Relations in Quantum Mechanics
All the fundamental quantum-mechanical commutators involving the Cartesian components of position, momentum, and angular momentum are enumerated. Commutators of sums and products can be derived using relations such as and . For example, the operator =++ obeys the commutation relations .
[A,B+C]=[A,B]+[A,C]
[A,BC]=B[A,C]+[A,B]C
