By means of the linear response method, the surface-dressed optical Bloch equations (SBE) for atoms absorbed on a solid surface are obtained. These SBE are different from the earlier oxies. The difference-lies in the fact that here the influences of the solid surface on the spontaneous decay rate and the Lamb shift of the adsorbed atoms have been taken into account. Using the SBE and the regression theorem, the resonance fluorescence spectrum for the adatoms are obtained. Through analyzing these spectrum numerically,...

By means of the linear response method, the surface-dressed optical Bloch equations (SBE) for atoms absorbed on a solid surface are obtained. These SBE are different from the earlier oxies. The difference-lies in the fact that here the influences of the solid surface on the spontaneous decay rate and the Lamb shift of the adsorbed atoms have been taken into account. Using the SBE and the regression theorem, the resonance fluorescence spectrum for the adatoms are obtained. Through analyzing these spectrum numerically, it is found that the solid surface will exert a significant influences both on the sidebands and peak hights. Namely, when the adatoms approach the surface, the distance between the two sidebands will become larger and the height for each peak will go down until the peaks disappear one by one.

本文借助于线性响应理论方法求得固体表面附近原子的光学布洛赫(Bloch)方程。借助于光学布洛赫方程和量子回归定理,求得了吸附原子的共振荧光谱。通过对该谱的数值分析可得出下述结论:固体表面的存在将对光谱中峰的高度以及两个边带的位置产生明显的影响。当被吸附的原子非常接近固体表面时,两个边带会向两侧移动,其中一个几乎消失,同时各个峰的高度也会大幅度降低。

An efficient Sisyphus cooling and geometric cooling of three level atoms in blue detuned evanescent light wave are discussed, and the kinetics processes of atom cooling in a pyramidal and conical hollow trap is studied by Monte Carlo simulation.The results shows that (1) the atom loss rate is decreased with the increase of evanescent wave laser power, (2) the final equilibrium temperature of atoms in the pyramidal trap is decreased as the reduce of detuning δ, and (3) there is a larger error between the Monte Carlo results and theoretically estimated ones when the judged width of evanescent light wave is not wide enough. In addition, under the same conditions, the pyramidal atom trap is more efficient than the conical atom trap, which can obtain a lower atomic temperature and higher atomic density.

讨论了三能级原子在消逝波光场作用下的Sisyphus冷却和几何冷却机制, 通过蒙特卡罗(Monte-Carlo)方法分别模拟了消逝波光场在方锥形势阱和圆锥形势阱两种情况下对原子冷却的动力学过程, 并计算了原子在不同的失谐量、激光功率及消逝波的判断宽度下的冷却情况。结果表明, 增大消逝波的激光功率能有效地减少原子的损耗, 但对冷却结果影响不大; 而消逝波的判断宽度不够宽时, 结果偏差较大; 对于方锥形势阱, 失谐量越小, 原子的最终温度也越低; 在其它条件相同的情况下, 方锥形势阱比圆锥形势阱更有效, 原子能达到更低的温度和更高的密度, 因而在原子光学, 如原子干涉仪、原子激光等应用中更为有用。
