Berry Phase of Two Impurity Qubits as a Signature of Dicke Quantum Phase Transition

In this paper, we investigate the effect of the Dicke quantum phase transition on the Berry phase of the two impurity qubits. The two impurity qubits only have dispersive interactions with the optical field of the Dicke quantum system. Therefore, the two impurity qubits do not affect the ground stat...
