    "abstract": "We suggest that low-lying eigenvalues of realistic quantum many-body\nhamiltonians, given, as in the nuclear shell model, by large matrices, can be\ncalculated, instead of the full diagonalization, by the diagonalization of\nsmall truncated matrices with the exponential extrapolation of the results. We\nshow numerical data confirming this conjecture. We argue that the exponential\nconvergence in an appropriate basis may be a generic feature of complicated\n(\"chaotic\") systems where the wave functions are localized in this basis.",
