In this paper, we show that if the density matrix of a pure Bloch state is averaged over the common phase, which connects the excited state of every atom with its ground state, the result is identical to a mixture of Dicke states with r=N/2 and a narrowly peaked distribution of m. It follows that Dicke states are essentially ...
