... Because of this extra sign and it has to be zero. In deriving this result, we have used only the symmetry property of the initial, final state and that of the perturbation operator. Here we encounter an important concept. That is, operators, just like states, can transform under symmetry and form re ...

... microlocalized outside a larger bounded domain (these properties depend on the choice of the symbol a(x1 , ξ0 )). As a result, the spectrum of M (T, h) is contained in the unit disk, and its effective rank is ≤ Ch−d (according to the handwaving argument that one quantum state occupies a volume ∼ hd ...

... Therefore, ut restricts to a unitary ut : Et → Et0 (with inverse u∗t = u∗t ¹ Et0 , of course). Moreover, identifying E ¯ Et = E = E ¯ Et0 , we find ut (x ¯ xt ) = ut ϑt (xξ ∗ )xt = ϑ0t (xξ ∗ )ut xt = x ¯ ut xt . It follows that (a ¯ idEt0 )ut = ut (a ¯ idEt ) for all a ∈ Ba (E). Specializing to a = ...

... Consider a macroscopic simple harmonic oscillator, and to keep things simple assume there are no interactions with the rest of the universe. We know how to describe the motion using classical mechanics: for a given initial position and momentum, classical mechanics correctly predicts the future path ...
