Physical Review D
We analyze and compare candidate crystal structures for the crystalline color superconducting phase that may arise in cold, dense but not asymptotically dense, three-flavor quark matter. We determine the gap parameter Delta and free energy Omega(Delta) for many possible crystal structures within a Ginzburg-Landau approximation, evaluating Omega(Delta) to order Delta^6. In contrast to the two-flavor case, we find a positive Delta^6 term and hence an Omega(Delta) that is bounded from below fordoi:10.1103/physrevd.74.094019 fatcat:xarv4gb6ezd77pia56a372bgkq
