For extended observables, covering a phase space area of many times Planck’s constant, both classical and quantal distributions are Gaussian. If the observable is a projection onto a single state or an incoherent projection onto several states classical and quantal distribution differ, but the mean and the variance are still obtainable from classical considerations. | | Source: | arXiv, nlin.CD/0008022 | | Services: | Forum | Review | PDF | Favorites | |
