Dicke states and Bloch states

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...
