... the proportionality constant is the reduced Planck constant ~ and thus we naturally get the de Broglie relation Rt (p̄) ≡ ~/Ē(p̄) = 1/ω̄(p̄). Since the period is related to the inverse of the fundamental energy Ē, and not to the inverse of an invariant mass as in the KK theory, the compactificatio ...

What a state function isn`t
... the state function plays a role in quantum mechanics that is analogous to that played by the trajectory in classical mechanics: it is the basic mathematical element, the state descriptor, of the theory. But the identification must end with this analogue! A wave function is not a trajectory. My point ...

Group Problems #27 - Solutions Wednesday, November 2 Problem 1
... Since this is not equal to zero, the K̂ and x̂ do not commute, and we cannot simultaneously measure the particle’s kinetic energy and position simultaneously. So if we constrain our measurement to a particular value of position (x), then we will measure a spread in kinetic energy values when we repe ...
