论文摘要
从理论上讲，我们研究了锯齿波绝热通道（SWAP）在1D磁光陷阱（MOT）中的应用。与先前讨论的相关方法相反，我们的方法利用刺激的吸收和发射过程的重复循环来实现捕获和冷却，从而减少了光子散射引起的不良反应。具体而言，我们证明了该方法的冷却，缓慢和陷阱颗粒具有较少自发发射的光子，更高的力以及与传统的MOT方案相比，在使用相同狭窄的线宽过渡的时间时，我们的能力较少。我们计算可实现的相位空间压缩，并表征所得系统的平衡云大小和温度。
We investigate theoretically the application of Sawtooth Wave Adiabatic Passage (SWAP) in a 1D magneto-optical trap (MOT). As opposed to related methods that have been previously discussed, our approach utilizes repeated cycles of stimulated absorption and emission processes to achieve both trapping and cooling, thereby reducing the adverse effects that arise from photon scattering. Specifically, we demonstrate this method's ability to cool, slow, and trap particles with fewer spontaneously emitted photons, higher forces and in less time when compared to a traditional MOT scheme that utilizes the same narrow linewidth transition. We calculate the phase space compression that is achievable and characterize the resulting system equilibrium cloud size and temperature.
