• A nonzero atomic electric-dipole moment (EDM) at a level not far from current experimental limits would signify time-reversal violation from outside the Standard Model. EDMs are enhanced in atoms that have octupole-deformed nuclei. I report calculations of the time-reversal-violating nuclear Schiff moment - the quantity that induces an atomic EDM - in the octupole-deformed nucleus ^<225>Ra as well as in ^<199>Hg, a symmetrically shaped isotope with the best current experimental limit on its atomic EDM. Although the two calculations are very different, both include important effects of core polarization and estimates of uncertainty. The results are encouraging for EDM experiments in the light actinides.
