 Matter-era growth with reduced gravitational clustering strength

ID: matter-era-growth-with-reduced-gravitational-clustering-strength

During matter domination, the growing mode under a reduced clustering strength

1 - f

D (t) \propto t^{s (f)}, s (f) = \frac{- 1 + 25 - 24 f}{6} .

It grows more slowly than the standard

t^{2/3}

mode whenever

0 < f < 1
