Large-scale structure in superfluid Chaplygin gas cosmology
  We investigate the growth of large-scale structure in the superfluid
Chaplygin gas (SCG) model. Both linear and non-linear growth, such as
$\sigma_8$ and the skewness $S_3$, are discussed. We find the growth factor of
SCG reduces to the EdS case at early times while differs from the $\Lambda$CDM
case in the large $a$ limit. We also find there will be much stricture growth
on large scales in the SCG scenario than in $\Lambda$CDM and the variations of
$\sigma_{8}$ and $S_3$ between SCG and $\Lambda$CDM can not be discriminated.
