摘要：
我们通过将塞曼效应与阿秒瞬态吸收光谱（ATAS）相结合，展示了中性原子中电子轨道角动量（OAM）的极化。利用密度矩阵模拟，我们证明在氦原子中，1s2p态中mj=-1与mj=1之间的吸收概率不对称性可以通过调节红外（IR）与极紫外（XUV）场之间的时间延迟、所施加静态磁场的强度以及激光偏振方向与磁场方向之间的夹角来精确控制。该方法在量子计算、量子通信和自旋电子学等多个领域具有重要影响。此外，它为操控化学反应控制、定制物质磁性质以及实现新型激光发射等应用的发展铺平了道路。
英文摘要：
We demonstrate the polarization of electron orbital angular momentum (OAM) in neutral atoms by integrating the Zeeman effect with attosecond transient absorption spectroscopy (ATAS). Using density matrix simulations, we show that in a helium atom, the absorption probability asymmetry between mj=-1 and mj = 1 in the 1s2p state can be precisely controlled by adjusting the time delay between infrared (IR) and extreme ultraviolet (XUV) fields, the strength of an applied static magnetic field, as well as the angle between laser polarization and magnetic field direction. This approach has significant implications across various fields, including quantum computing, quantum communication, and spintronics. Moreover, it paves the way for advancements in applications such as manipulating chemical reactions control, tailoring the magnetic properties of matter, and enabling novel laser emissions.
