Angular momentum operator

Following our previous discussion on compatible observables, this means that the components are not compatible observables. We cannot measure, for instance, Lx and Ly simultaneously, and we do not have a basis ...

Is there a problem with quantum wormhole states in N= 1

However, it seems more natural to study quantum wormhole states, i.e., solutions of the Wheeler-DeWitt equation [16,28-31]. It is ...
