    "abstract": "The light-induced frequency shift due to the hyperpolarizability (i.e. terms\nof second-order in intensity) is studied for a forbidden optical transition,\n$J$=0$\\to$$J$=0. A simple universal dependence on the field ellipticity is\nobtained. This result allows minimization of the second-order light shift with\nrespect to the field polarization for optical lattices operating at a magic\nwavelength (at which the first-order shift vanishes). We show the possibility\nfor the existence of a magic elliptical polarization, for which the\nsecond-order frequency shift vanishes. The optimal polarization of the lattice\nfield can be either linear, circular or magic elliptical. The obtained results\ncould improve the accuracy of lattice-based atomic clocks.",
