THE PROPERTIES OF DISPLACED BINOMIAL STATES AND DISPLACED NEGATIVE BINOMIAL STATES AND THEIR INTERACTION WITH TWO-LEVEL ATOMS
位移二项式态与位移负二项式态的性质及其与二能级原子的相互作用

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 Sussking-Glogower phased state. Finally, we study the dynamical evolution of atomic population inversion in the intensity-dependent interaction between these two states and two-level atoms.
