标题： Dimer-atom-atom recombination in the universal four-boson system

摘要： 四体系统中具有共振相互作用的二聚体-原子-原子再结合过程被研究。 描述使用了四粒子转移算符的精确Alt、Grassberger和Sandhas方程，在动量空间框架中求解。 计算了二聚体-二聚体和原子-三聚体通道对超冷二聚体-原子-原子再结合率的贡献。 二聚体-原子-原子再结合率大大超过三原子再结合率。 显示英文摘要

摘要： The dimer-atom-atom recombination process in the system of four identical bosons with resonant interactions is studied. The description uses the exact Alt, Grassberger and Sandhas equations for the four-particle transition operators that are solved in the momentum-space framework. The dimer-dimer and atom-trimer channel contributions to the ultracold dimer-atom-atom recombination rate are calculated. The dimer-atom-atom recombination rate greatly exceeds the three-atom recombination rate.
