 Abstract: We investigate the thermodynamic limit of Dicke superradiance. We find an
expression for the system's density matrix that we can prove is exact in the
limit of large atom numbers N. This is in contrast to previously known
solutions whose accuracy has only been established numerically and that are
valid only for a range of times. We also introduce an asymptotically exact
solution when the system is subject to additional incoherent decay of
excitations as this is a common occurrence in experiment.
