    "abstract": "A black-body radiation (BBR) shifts of (nsnp ^3P_0) - (ns^2 ^1S_0) clock\ntransition in divalent atoms Mg, Ca, Sr, and Yb are evaluated. A theory of\nmultipolar BBR shifts is developed and its implications are discussed. At room\ntemperatures, the resulting uncertainties in the BBR shifts are relatively\nlarge and substantially affect the projected 10^{-18} fractional accuracy of\nthe optical-lattice-based clocks.",
