| Abstract: | The properties of the phase evolution of an initially squeezed vacuum in the Jaynes-Cummings model are studied by using the Pegg-Barnett phase theory. The phase probability distribution and variance are calculated for weal squeezing. The curres of evolution of the phas probability distribution are given on a polar diagram. The influenses of an atom interacting with squeezed vacuum on the phase properties are discused. |
