Reply to Comment on "Superfluid stability in the BEC-BCS crossover" by   Sheehy and Radzihovsky
  The reason behind the discrepancy between the phase diagrams of our earlier work [1] and the comment of Sheehy and Radzihovsky [2] is discussed. We show that, in contrast to what is claimed in [2], the requirement of positive susceptibility is sufficient to rule out states that are local maximum of the free energy (as a function of the order parameter $\Delta$
