摘要:

本文报道了在射频场作用下,在反弛豫涂层的汽室中对$^{87}$ Rb原子D2线的非线性磁光旋转(NMOR)的测量结果。实验NMOR信号作为RF场频率的函数,为各种RF场功率进行比较的理论模型的基础上的密度矩阵形式主义。实验和理论之间的比较,使基态原子自旋极化动力学的理解,说明使用的原子角动量的概率分布图。

英文摘要:

We report measurements of nonlinear magneto-optical rotation (NMOR) for the D2 line of $^{87}$Rb atoms in an antirelaxation-coated vapor cell in the presence of a radio-frequency (rf) field. The experimental NMOR signals as a function of rf field frequency for various rf field powers are compared to a theoretical model based on the density-matrix formalism. The comparison between experiment and theory enables understanding of the ground-state atomic spin polarization dynamics, illustrated using plots of the probability distribution of the atomic angular momentum.
