Pseudogap phenomenon near the phase transition from $p_x$- to $p_x+ip_y$-wave Fermi superfluid

We discuss an ultracold superfluid Fermi gas with a $p$-wave Feshbach resonance (FR). In this system, it has been predicted that the split of $p_x$-, $p_y$-, and $p_z$-wave channels in the $p$-wave FR by a dipole-dipole interaction leads to multi-superfluid phases. While the $p_x$-wave state appears below $T_{\rm c}$, the $p_x+ip_y$-wave state is expected to become more stable below a certain temperature ($\equiv T_{\rm c}^{p_x+ip_y}
