The research is focused on the calculation of three-body recombination rates at ultra-cold collision energies. These rates are required to study and understand bosonic and fermionic condensation of atoms in traps. The principal investigator will calculate the necessary potential energy surfaces and then apply a hyperspherical coupled channel expansion, including all necessary coupling terms, to compute the cross sections.

研究的重点是在超冷碰撞能量的三体复合率的计算。 研究和理解陷阱中原子的玻色子和费米子凝聚需要这些速率。 主要研究者将计算必要的势能面，然后应用超球面耦合通道展开，包括所有必要的耦合项，以计算横截面。
