摘要
提出并研究两种新的量子光场态：位移二项式态和位移负二项式态．讨论了两种量子态的光子数分布、亚泊松分布特性．结果表明：位移二项式态是介于相干态与位移粒子数态之间的一种量子中间态，在不同参数下可表现亚泊松分布和超泊松分布；位移负二项式态是介于相干态与位移ＳｕｓｋｉｎｄＧｌｏｇｏｗｅｒ位相态之间的量子中间态，它只表现超泊松分布．
Abstract In this article,we propose two new quantum field states,displaced binomial state and displaced negative binomial state.Their photon number distributions and sub Poissonian properties are discussed.The results show that the displaced binomial state is a kind of intermediate quantum state between the coherent state and displaced number state and it may be sub Poissonian and super Poissonian at different parameters.The displaced negative binomial state is always super Poissonian and is an intermediate state between coherent state and displaced Susskind Glogower phase state.Finally,we study the dynamical evolution of atomic population inversion in the intensity dependent interaction between these two states and two level atoms.
