Abstract

We introduce the inverse annihilation and creation operators â -1 and â +-1 by their actions on the number states. We show that the squeezed vacuum exp(½;ξâ +2]|0> and squeezed first number state exp[½;ξâ +2]|n=1> are respectively the eigenstates of the operators (â †-1 â) and (ââ +-1) with the eigenvalue ξ.
