摘　　要：对处于相干态光场的非线性Tavis-Cummings模型中Pancharatnam相进行了理论上和数值上的研究,并获得了这个量子系统中Pancharatnam相的精确表达式.分析表明:两原子之间的偶极相互作用强度能改变Pancharatnam相演化的周期,并证明了Pancharatnam相包含原子和场的信息,同时,非线性的出现会导致Pancharatnam相的演化出现混沌行为.The Pancharatnam phase of a Tavis-Cummings model with the coherent state in Kerr medium is investigated theoretically and numerically. An exact expression of the Pancharatnam phase under this general system is obtained. The numerical results show that the dipole-dipole coupling strength between two atoms can change the quasi-period of the Pancharatnam phase evolution, and it is also proved that the Pancharatnam phase contains the information of atoms and the field. In the nonlinear interaction regime, the nonlinearity can cause the chaotic behavior of the Pancharatnam phase.
