kth-order antibunching effect for a new kind of excited even and oddq-coherent states
Jiang Jun-qin · Chinese Physics C · 2010
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.
