    • Abstract


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