  We explore the spontaneous generation and decay of quantum correlations
between two identical atoms coupled to a common Markovian environment in the
presence of electromagnetic field modes. For this purpose, we analyze the
dynamics of quantum correlations by employing the concurrence, the trace
quantum discord and the local quantum uncertainty, for collective Dicke states.
It is shown that the collective damping and dipole-dipole interaction plays a
key role in enhancing non-classical correlations during the process of
intrinsic decoherence. The quantum correlations can be maintained over a long
time but for small distance between the two atoms.
