Electric dipole polarizabilities of alkali metal ions from perturbed relativistic coupled-cluster theory

We use the perturbed relativistic coupled-cluster theory to compute the static electric dipole polarizabilities of the singly ionized alkali atoms, namely, Na${}^{+}$, ${}^{+}$, Rb${}^{+}$, Cs${}^{+}$ and Fr${}^{+}$. The computations use the Dirac-Coulomb-Breit Hamiltonian with the no-virual-pair approximation and we also estimate the correction to the static electric dipole polarizability arising from the Breit interaction.
