我们研究了具有外部自旋轨道势和短程两体相互作用的各向同性谐振陷阱中自旋1/2费米子的两体谱。使用截断的总角动量本征态的基础上，非微扰结果的实验现实形式的自旋-轨道耦合：一个纯粹的Rashba耦合，Rashba和Dresselhaus耦合在相等的部分，和Weyl型耦合。该技术很容易适用于玻色子系统和其他形式的自旋轨道耦合。
We explore the two-body spectra of spin-$1/2$ fermions in isotropic harmonic traps with external spin-orbit potentials and short range two-body interactions. Using a truncated basis of total angular momentum eigenstates, non-perturbative results are presented for experimentally realistic forms of the spin-orbit coupling: a pure Rashba coupling, Rashba and Dresselhaus couplings in equal parts, and a Weyl-type coupling. The technique is easily adapted to bosonic systems and other forms of spin-orbit coupling.
