... Prove the theorems for unitary operators stated in Le Bellac, page 52, section 2.3.4. Note: the proofs of a) and b) are quite simple, and are very similar to the proofs given in class for the case of Hermitian operators. Part c) is actually worked out in the text! It is important to note the final r ...

3.1 The correspondence principle
... The fraction of each Eigenvector to the sum of all states will change generally as a function of time. ⇒ The state of a system will normally change in time. REMARKS: • In physics the formalism of energy is much more fundamental than the formalism of using forces. • All forces which apply to an elect ...
