The phase diagram of a homogenous ultracold Fermi gas with spin polarization is studied at unitarity.In the framework of Landau's phase-transition theory,the thermodynamic grand potential is expanded to the sixth order in the order parameter,and coefficients of each order are determined.The tricritical point in the temperature-polarization plane is obtained.Above the critical point,the second-order phase-transition line between the superfluid and the normal phase is determined.Below the… CONTINUE READING
