    "abstract": "We explore the role played by the quantum relative phase in a well-known\nmodel of atom-field interaction, namely, the Dicke model. We introduce an\nappropriate polar decomposition of the atom-field relative amplitudes that\nleads to a truly Hermitian relative-phase operator, whose eigenstates correctly\ndescribe the phase properties, as we demonstrate by studying the positive\noperator-valued measure derived from it. We find the probability distribution\nfor this relative phase and, by resorting to a numerical procedure, we study\nits time evolution.",
