    "abstract": "We obtain the ground-state energy level and associated geometric phase in the\nDicke model analytically by means of the Holstein-Primakoff transformation and\nthe boson expansion approach in the thermodynamic limit. The non-adiabatic\ngeometric phase induced by the photon field is derived with the time-dependent\nunitary transformation. It is shown that the quantum phase transition\ncharacterized by the non-analyticity of the geometric phase is remarkably of\nthe first-order. We also investigate the scaling behavior of the geometric\nphase at the critical point, which can be measured in a practical experiment to\ndetect the quantum phase transition.",
