Collapse and revivals for the binomial field distribution

Abstract

The exact representation of the atomic inversion in the Jaynes-Cummings model as an integral over the Hankel contour is used. For a field in a binomial state, the integral is evaluated using the saddle point method. Simple approximate analytical expressions for collapse and revivals are obtained.Comment: 5 pages, 1 figures. arXiv admin note: substantial text overlap with arXiv:2307.0783
