Abstract

We explore the quantum criticality in a one-dimensional quantum network, where adjacent nodes are connected by a fiber and each node consists of a cavity doped with N two-level atoms. We investigate the phase diagrams for cases of different atom numbers on resonance by making use of the mean-field approximation and find that both the fidelity and entanglement entropy for the ground state have dramatic changes near the critical points. Finally, the photon population imbalance of adjacent cavities is analytically explored via the two-node quantum network as the forerunner of phase transition.
