| Abstract: | We introduce the inverse annihilation and creation operatorsa −1 anda +-1 by their actions on the number states. We show that the squeezed vacuum exp(1/2;ξa +2]|0> and squeezed first number state exp[1/2;ξa +2]|n=1> are respectively the eigenstates of the operators (a †−1 a) and (aa +-1) with the eigenvalue ξ. |
| Keywords: | Coherent states squeezed states squeezed vacuum two-photon annihilation operators |
