摘　　要：运用全量子理论研究了双模竞争模型中光子的统计性质,讨论了原子与双模光场相互作用的相对耦合强度对光子统计性质的影响。数值计算结果表明,双模光场的光子周期性地呈现反聚束效应,光场两模之间总是呈现负相关,并且,这种相关大部分时间为非经典相关。The statistic properties of photon in the two-mode competition model are studied from the perspective of quantum theory, and the influence of relative competing strength between the atom and the two-mode field on the statistic properties of photon is discussed. Tile results of numerical calculations indicate that the photon antibunching of the two- mode field appears periodically. On the other hand, the correlation of the two modes of light is aluays negative and this kind of correlation is non-classical in most of the time.
