标题： Optical stimulated slowing of polar heavy-atom molecules with a constant beat phase

摘要： 极性重原子分子已被广泛认为是精密测量和基础物理测试的有希望的候选者。 更慢的分子束可以增加相互作用时间，从而导致更灵敏的测量。 在这里，我们理论上传播了通过具有恒定拍频相位的相干光学双色力对重原子分子进行受激纵向减速的可能性。 以YbF分子为例，我们展示了在适度条件下，通过相位补偿方法实现重分子的快速和短距离减速是可行的。 具有前向速度为120 m/s的YbF分子束可以在3.5厘米的距离内减速至10 m/s以下，并且每个行波的激光辐照度为107.2 W/cm$^2$。 我们还提供了一种简单的方法来估算BCF在其他一些重分子上的性能，这对于快速评估受激减速实验的可行性是有帮助的。 我们提出的减速方法可能是一种有前景的方法，可以突破传统减速方案中分子可加载到MOT中的空间限制或有限捕获效率，从而为显著提高精密测量灵敏度开辟可能性。 显示英文摘要

摘要： Polar heavy-atom molecules have been well recognized as promising candidates for precision measurements and tests of fundamental physics. A much slower molecular beam to increase the interaction time should lead to a more sensitive measurement. Here we theoretically demonstrate the possibility of the stimulated longitudinal slowing of heavy-atom molecules by the coherent optical bichromatic force with a constant beat phase. Taking the YbF meolecule as an example, we show that a rapid and short-distance deceleration of heavy molecules by a phase-compensation method is feasible with moderate conditions. A molecular beam of YbF with a forward velocity of 120 m/s can be decelerated below 10 m/s within a distance of 3.5 cm and with a laser irradiance for each traveling wave of 107.2 W/cm$^2$. We also give a simple approach to estimate the performance of the BCF on some other heavy molecules, which is helpful for making a rapid evaluation on the feasibility of the stimulated slowing experiment. Our proposed slowing method could be a promising approach to break through the space constraint or the limited capture efficiency of molecules loadable into a MOT in traditional deceleration schemes, opening the possibility for a significant improvement of the precision measurement sensitivity.
