  We report two phenomena, induced by dynamical correlations, that occur during
the free cooling of a two-dimensional mixture of inelastic hard disks. First,
we show that, due to the onset of velocity correlations, the ratio of the
kinetic energies associated with the two species changes from the value
corresponding to the homogeneous cooling state to a value approximately given
by the mass ratio m_1/m_2 of the two species. Second, we report a novel
segregation effect that occurs in the late stage of cooling, where
interconnected domains appear. Spectral analysis of the composition field
reveals the emergence of a growing characteristic length.
