Reply on `comment on our paper `Single two-level ion in an anharmonic-oscillator trap: Time evolution of the Q function and population inversion ''

Abstract

We show here that the model Hamiltonian used in our paper for ion vibrating in a q-analog harmonic oscillator trap and interacting with a classical single-mode light field is indeed obtained by replacing the usual bosonic creation and annihilation operators of the harmonic trap model by their q-deformed counterparts. The approximations made in our paper amount to using for the ion-laser interaction in a q-analog harmonic oscillator trap, the operator $F_{q}=exp{-(|ε|^2}/2)}exp{iεA^{\dagger}}exp{iεA}$, which is analogous to the corresponding operator for ion in a harmonic oscillator trap that is $F=exp{-(|ε|^2 /2)}exp{iεa^{\dagger }}exp{iεa}$. In our article we do not claim to have diagonalized the operator, $F_q = exp{i ε(A^{\dagger}+A)}$, for which the basis states |g,m> and |e,m> are not analytic vectors.
