@article{Usui2020SpinorbitCI, title={Spin–orbit coupling in the presence of strong atomic correlations}, author={Ayaka Usui and Thom{\'a}s Fogarty and Steve Campbell and Simon A. Gardiner and Thomas Busch}, journal={New Journal of Physics}, year={2020}, volume={22} }

We explore the influence of contact interactions on a synthetically spin–orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show that a regime exists in which the competition between the contact and spin–orbit interactions results in the emergence of a ground state that contains a significant contribution from the anti-symmetric spin state. This ground state is unique to few-particle systems and does not exist in the mean-field regime. The…
