The interaction of an atom with a sub-Poissonian single field mode

Research output: Contribution to journalArticlepeer-review


The resonant interaction of a single atom with a single quantized field mode characterized by sub-Poissonian statistics is compared with its interaction with a coherent field mode. Two models are considered: the Jaynes-Cummings model (JCM) and the Raman-coupled model (RCM). Quadrature squeezing variances and photon number uncertainties are evaluated. In the JCM, sub-Poissonian field statistics lead to longer collapse times and more complete revivals than Poissonian statistics. In the RCM, which is characterized by periodic collapses and revivals, the collapse time is longer for sub-Poissonian fields.
