Statistic properties of thermal radiation field in K-photon Jaynes-Cummings model

Yun‐Jie Xia

Interaction of thermal radiation field with atom are studied. We find that the field may exhibition photon antibunching and photon sub-Poissonian distribution. We also study the photon statistic properties of thermal radiation field in the process. It can be find that average photon number of thermal radiation field and multi-photon transition process have intense influence on the non-classical properties.

Bounds on sub-Poissonian field statistics in the Jaynes-Cummings model

Mark S. Hillery

The Jaynes-Cummings model describes the interaction between a two-level atom and a single mode of the radiation field. This system has a conservation law which restricts its dynamics. On the basis of this conservation law alone one can make useful statements about the photon statistics of the fields which arise in the model. Two cases are considered. In the first the field is initially in a coherent state. Here it is found that the field statistics become less sub-Poissonian as the amplitude of the initial state increases. The case of an initial thermal state is also considered. In that situation, if the average number of photons present in the initial state is greater than 2.55, then the field statistics can never become sub-Poissonian.
