Abstract ： A simple numerical method is developed to calculate the Floquet eigenstate and the quasienergy; the quantum Wigner function and the Husimi function in phase space in the atomic stabilization dynamics have also been studied Within the Kramers-Henneberger reference frame. The characteristic Wehrl entropy is introduced and used to measure the spreading and ionization of those obtained Floquet eigenstate wave packets.
