Efimov physics and universal trimers in spin-orbit-coupled ultracold atomic mixtures

Zhe-Yu Shi, Hui Zhai, Xiaoling Cui

We study the two-body and three-body bound states in ultracold atomic mixtures with one of the atoms subjected to an isotropic spin-orbit (SO) coupling. We consider a system of two identical fermions interacting with one SO-coupled atom. It is found that there can exist two types of three-body bound states, Efimov trimers and universal trimers. The Efimov trimers are energetically less favored by the SO coupling, which will finally merge into the atom-dimer threshold as increasing the SO-coupling strength. Nevertheless, these trimers exhibit a discrete scaling law incorporating the SO-coupling effect. On the other hand, the universal trimers are more favored by the SO coupling. They can be induced at negative $s$-wave scattering lengths and with smaller mass ratios than those without SO coupling. These results are obtained by both the Born-Oppenheimer approximation and exact solutions from three-body equations.

Universal and Efimov trimers in an alkaline-earth-metal and alkali-metal gas mixture with spin-orbit coupling

Qing Ji, Ren Zhang, Wei Zhang

We exactly solve the two-body and three-body problems in the mixture of alkaline-earth-metal(like) (AE) and alkali-metal atomic gases in the presence of three-dimensional isotropic spin-orbit (SO) coupling. The SO coupling is implemented by the Raman scheme that couples the ground state of the AE atom with different nuclear spin. The interaction between AE and alkali-metal atoms is tuned to be near resonant by Feshbach resonance, while the interaction between the two AE atoms is negligible. We present the Skorniakov--Ter-Martirosian (STM) equation for the three-body system composed of two SO coupled AE atoms and one alkali-metal atom. By solving the STM equation in the zero angular momentum sector, we obtain the energy spectrum and find a nonuniversal Efimov trimer and a universal Kartavtsev-Malykh (KM) trimer in different parameter windows of the mass ratio. In the region where the KM trimer is present, strong SO coupling can stabilize the KM trimer to be the ground state, such that experimental realization and observation can be expected.

Universal Trimers Induced by Spin-Orbit Coupling in Ultracold Fermi Gases

Zhe-Yu Shi, Xiaoling Cui, Hui Zhai

In this Letter we address the issue of how synthetic spin-orbit (SO) coupling can strongly affect three-body physics in ultracold atomic gases. We consider a system which consists of three fermionic atoms, including two spinless heavy atoms and one spin-1/2 light atom subjected to an isotropic SO coupling. We find that SO coupling can induce universal three-body bound states with a negative s-wave scattering length at a smaller mass ratio, where no trimer bound state can exist if in the absence of SO coupling. The energies of these trimers are independent of the high-energy cutoff, and therefore they are universal ones. Moreover, the resulting atom-dimer resonance can be effectively controlled by SO coupling strength. Our results can be applied to systems like a 6Li and 40K mixture.
