We characterize all position and momentum observables on R and on R^3, i.e. all observables satisfying a suitable covariance property under the action of the Galilei group. We show that each position (respectively, momentum) observable is a fuzzy version of sharp position (resp., momentum). We study some operational properties of position and momentum observables and discuss their covariant joint observables.

Abstract
We characterize all position and momentum observables on R and on R^3, i.e. all observables satisfying a suitable covariance property under the action of the Galilei group. We show that each position (respectively, momentum) observable is a fuzzy version of sharp position (resp., momentum). We study some operational properties of position and momentum observables and discuss their covariant joint observables.File in questo prodotto:
