    "abstract": "We present a general approach within the relativistic coupled-cluster theory\nframework to calculate exactly the first order wave functions due to any rank\nperturbation operators. Using this method, we calculate the static dipole and\nquadrupole polarizabilities in some alkali atoms and alkaline earth-metal ions.\nThis may be a good test of the present theory for different rank and parity\ninteraction operators. This shows a wide range of applications including\nprecise calculations of both parity and CP violating amplitudes due to rank\nzero and rank one weak interaction Hamiltonians. We also give contributions\nfrom correlation effects and discuss them in terms of lower order many-body\nperturbation theory.",
