多光子T-C模型中场的反聚束效应

Anti-bunching effect of the field in multiphoton Tavis-Cummings model

利用Tavis-Cummings模型,采用数值计算的方法,研究了耦合二能级原子通过多光子跃迁与相干态光场相互作用系统中光场的反聚束效应,讨论了原子间耦合强度和光场初始平均光子数的变化对场的反聚束效应的影响.研究结果表明:随光场初始平均光子数的增大,场的反聚束效应增强;随原子间耦合强度的增大,场的反聚束效应减弱.

Using Tavis-Cummings model, the anti-bunching effect of the field in interaction of two coupling two-level atoms with coherent state light field through multiphoton transition was studied. The influences of coupling constants between atoms and intial mean photon number of field on anti-bunching effect of the field were discussed. The results obtained by the numerical method show that with increasing of intial mean photon number of field the anti-bunching effect of the field is getting stronger, and with increasing of coupling constant between atoms the anti-bunching effect of the field is getting weaker.
