摘要
A new kind of even and odd coherent states i.e. the photon-added and photon-depleted states,can be obtained from acting boson inverse operators on the usual even and odd coherent states. The new states are the eigenstates of the operators a(-k) a(k 2) and a( - k) a(2) a( k), respectively. The results show that these states may reveal the anti-bunching and quantum squeezing effects.
