Ferromagnetic transition of a spin-orbit coupled dipolar Fermi gas at finite temperatureProject supported by the National Key Research and Development Project of China (Grant No. 2016YFA0301501)

We study the ferromagnetic transition of a two-component homogeneous dipolar Fermi gas with 1D spin-orbit coupling (SOC) at finite temperature. The ferromagnetic transition temperature is obtained as functions of dipolar constant λd, spin-orbit coupling constant λSOC and contact interaction constant...

Summary:We study the ferromagnetic transition of a two-component homogeneous dipolar Fermi gas with 1D spin-orbit coupling (SOC) at finite temperature. The ferromagnetic transition temperature is obtained as functions of dipolar constant λd, spin-orbit coupling constant λSOC and contact interaction constant λs. It increases monotonically with these three parameters. In the ferromagnetic phase, the Fermi surfaces of different components can be deformed differently. The phase diagrams at finite temperature are obtained.
