摘　　要：建立了q形变光场与级联型三能级原子相互作用的非线性理论,求得相互作用绘景中薛定谔方程的形式解及在其态下的期望值,利用数值计算揭示了q形变对场与三能级原子相互作用中场反聚束效应的影响．研究发现q偏离1的程度越大,q形变对场反聚束效应的调控能力越强,反映出q形变的非线性行为对量子相干性的干扰以及对量子特性的影响．当q→1时,恢复为普通线性理论．A nonlinear theoretical model of interaction between q-deformed light field and a cascade three-level atom has been constructed. The formal solution of SchrSdinger equation in the interactive representation and the expectation value of the interaction on such a state are obtained. Then, the influence of q deformation on photon antibunching effects is studied by numerical calculation. The results show that the more q deviates from 1, the, stronger controllability to antibunching effects the q deformation has. It reflects the effect of the nonlinear behavior of q deformation on quantum coherence and quantum properties. When q→1, the theory reduces to the normal linear theory.
