Classical and quantum Malus laws
Copyright policy )Classical and quantum Malus laws
The classical and the quantum Malus' Laws for light and spin are discussed. It is shown that for spin-1/2, the quantum Malus' Law is equivalent in form to the classical Malus' Law provided that the statistical average involves a quasi-distribution function that can become negative. A generalization of Malus' Law for arbitrary spin-s is obtained in the form of a Feynman path-integral representation for the Malus amplitude. The classical limit of the Malus amplitude for large s is discussed.
