| 摘 要： | 考虑单个二能级原子穿过两个空间分离的单模腔场.由于腔场与原子间的相互作用使得两个腔场间产生纠缠.研究原子质心运动的动能、腔长和腔间距对这种纠缠的影响.结果表明:在原子的动能较小时,原子通过双腔系统的几率较小,腔场间产生纠缠的几率也小;原子动能较大时,原子更容易隧穿双腔系统,腔场间产生的纠缠几率也较大.

| Abstract: | An two-level atom is considered passes through double spatially separated single-mode cavity fields and the influence of the center-of- mass motion of the atom is investigated, the length of the cavity and the separation between two cavities on entanglement between the cavity fields because of interaction between the atom and the cavity fields. It is found that in the case of ultra-cold atom, when k/k0<1, the probility that the atom passes through double cavity fields is small, and the entanglement is generated is small too. And when k/k0>1, the result is contraty. |
