³P₂ pairing near the transition temperature in neutron-star matter

Abstract:
We first find the minima of the general Ginzburg-Landau functional for ³P₂ pairing. The BCS functional lies in a region of the Ginzburg-Landau parameter space where the free energy is minimized by any unitary order parameter. We next estimate the strong-coupling corrections to the BCS functional for dense neutron matter. Using current theoretical values for the transition temperature and Landau parameters, we find that the strong-coupling functional remains in the same region of parameter space as the BCS functional.
