Contact Theory for Spin-Orbit-Coupled Fermi Gases
Author(s): Shi-Guo Peng, Cai-Xia Zhang, Shina Tan, and Kaijun Jiang
We develop the contact theory for spin-orbit-coupled Fermi gases. By using a perturbation method, we derive analytically the universal two-body behavior at short distance, which does not depend on the short-range details of interatomic potentials. We find that two new scattering parameters need to b...
