We present a simple and unifying picture that provides the energy and scattering length dependence for all inelastic three-body collision rates in the ultracold regime for three-body systems with short-range two-body interactions. Here, we present the scaling laws for vibrational relaxation, three-body recombination, and collision-induced dissociation for systems that support s-wave two-body collisions. These systems include three identical bosons, two identical bosons, and two identical fermions. Our approach reproduces all previous results, predicts several others, and gives the general form of the scaling laws in all cases.
我们展示了一幅简单且统一的图景,它给出了具有短程两体相互作用的三体系统在超冷区域中所有非弹性三体碰撞率的能量和散射长度依赖性。在此,我们给出了支持s波两体碰撞的系统的振动弛豫、三体复合以及碰撞诱导解离的标度律。这些系统包括三个相同的玻色子、两个相同的玻色子以及两个相同的费米子。我们的方法重现了所有先前的结果,预测了其他一些结果,并给出了所有情况下标度律的一般形式。
