Quantum Mechanics: Commutation 7 april 2009 I.Commutators: MeasuringSeveralProperties Simultaneously In classical mechanics, once we determine the dynamical state of a system, we can simultaneously obtain many di erent system properties (i.e., ve-locity, position, momentum, acceleration, angular/linear momentum, kinetic and potential energies

The basic canonical commutation relations then are easily summarized as xˆi ,pˆj = i δij , xˆi ,xˆj = 0, pˆi ,pˆj = 0. (1.5) Thus, for example, ˆx commutes with ˆy, z,ˆ pˆ. y . and ˆp. z, but fails to commute with ˆp. x. In view of (1.2) and (1.3) it is natural to deﬁne the angular momentum operators by Lˆ. x ≡ yˆpˆ
