The FFLO state with angle dependent Gap in Asymmetric Nuclear Matter    [PDF]

Xinle Shang, Wei Zuo

We consider the FFLO and ADG state together within the same model for the asymmetric nuclear matter. The arbitrary angles between the Cooper pair momentum and the symmetry axis are studied. We find the favored angle is either 0 or pi/2 which correspond to FFLO-ADG-Orthogonal and FFLO-ADG-Parallel state respectively. Furthermore, the FFLO-ADG-Orthogonal settles at weakly asymmetric case, while the FFLO-ADG-Orthogonal are favored for large asymmetry. The critical isospin-asymmetry alpha_{c}, where superfluid vanishes, increases largely by considering the Cooper pair momentum.
