A new kind of excited even q-coherent states (aq-1)m|αqe and excited odd q-coherent states (aq-1)m|αqo is constructed by acting with inverse boson operators on the even and odd q-coherent states. The m dependence of the kth-order antibunching effect is numerically studied for k = 2, 3, 4, 5.It is shown that the kth-order antibunching effect enhances as m increases. The larger k, the quicker the antibunching effect enhances.

A new kind of excited even q-coherent states (a−1q)m|αeq and excited odd q-coherent states (a−1q)m|αoq is constructed by acting with inverse boson operators on the even and odd q-coherent states. The m dependence of the kth-order antibunching effect is numerically studied for k = 2, 3, 4, 5. It is shown that the kth-order antibunching effect enhances as m increases. The larger k, the quicker the antibunching effect enhances.

Using the numerical method,the antibunching effects of a new kind of odd and even nonlinear coherent states in a finite-dimensional Hilbert space are studied.The results show that the new kind of odd nonlinear coherent state exhibits antibunching effect and the new kind of even nonlinear coherent state does not exhibits antibunching effect in a finite-dimensional Hilbert space.
