Abstract

We introduce a picture of quantum dynamics in which the representation basis vectors are the quantities that evolve, instead of state vectors or operators. These vectors allow us to pick the parts of a probability density that correspond to some values of energy or time, providing us with energy and time representations. The properties of these representations are analyzed and an application to the free particle is presented.
