    "abstract": "An iterative algorithm is presented for solving the RPA equations of linear\nresponse. The method optimally computes the energy-weighted moments of the\nstrength function, allowing one to match the computational effort to the\nintrinsic accuracy of the basic mean-field approximation, avoiding the problem\nof solving very large matrices. For local interactions, the computational\neffort for the method scales with the number of particles N_p as O(N_p^3).",
