Exact solvability, non-integrability, and genuine multipartite entanglement dynamics of the Dicke model

In this paper, the finite-size Dicke model of arbitrary number of qubits is solved analytically in a unified way within extended coherent states. For the $N=2k$ or $2k-1$ Dicke models ( k is an integer), the G -function, which is only an energy dependent $k\times k$ determinant, is derived in a tran...
