我们提出了一个严格的研究极性分子和原子在微波激光场低温碰撞。我们的计算表明，微波腔中分子的非弹性弛豫可能是由原子-分子相互作用势的各向异性激发的光子的碰撞诱导吸收引起的。结果表明，中等强度的微波激光场可以有效地控制温度低于1k的分子碰撞。
We present a rigorous study of low-temperature collisions of polar molecules and atoms in a microwave laser field. Our calculations show that inelastic relaxation of molecules in a microwave cavity may occur through collision-induced absorption of photons stimulated by the anisotropy of the atom-molecule interaction potential. Our results indicate that molecular collisions at temperatures below 1 K can be efficiently manipulated with microwave laser fields of moderate strength.
