THE AMPLITUDE-N-TH POWERED SQUEEZING OF AN ELECTROMAGNETIC FIELD IN THE MULTIPHOTON JAYNES-CUMMINGS MODEL INTERACTING WITH THE SUPERPOSITION STATE

We have studied the properties of the amplitude-N-th powered squeezing of an elec-tromagnetic field in the k-photon Jaynes-Cummings model of an atom initially being in the ground state and coupling with the superposition state. The results show that, under the condition of n≥k, where n is the photon number of the superposition state, the field exhibits not only the amplitude-N = n-th powered squeezing but also the amplitude-N = (n/2)-th powered squeezing for even n. The variations of the amplitude-N-th powered squeezing of the field with the powers N and k are discussed.
