Abstract

Correction to: Nature Physics, published online 22 August 2022. The initially published version of the paper contained an error. Matrix elements in the normal-ordering procedure of the three-nucleon force were computed incorrectly, which influences results presented in Fig. 3a. The figure has been corrected, and the Source Data file for Fig. 3 has been replaced. These changes have no effect on the conclusions drawn in the article regarding the neutron skin thickness of 208Pb and other properties of finite nuclei. The fourth sentence in the Discussion now starts “We find that both Rskin (208Pb) = 0.14–0.20 fm and the slope parameter L = 38–69 MeV are strongly correlated with scattering in the 1S0 partial wave for laboratory energies around 50 MeV”, replacing the original wording “We find that both Rskin (208Pb) = 0.14–0.20 fm and the slope parameter L = 37–66 MeV are strongly correlated with scattering in the 1S0 partial wave for laboratory energies around 50 MeV”. The error also affects results presented in Methods, Extended Data Table 2 and Extended Data Figs. 6–8. The final two sentences in the third paragraph of the “Bayesian machine learning error model” section (in Methods) now read “In this work, we find (Formula presented.) and lPNM = 0.88 fm−1 for pure neutron matter and (Formula presented.) and (Formula presented.) fm−1 for symmetric nuclear matter. This leads to Q = 0.41 when estimating the model errors for E/A in 48Ca and 208Pb”, replacing the original wording “In this work, we find (Formula presented.) and (Formula presented.) fm−1 for pure neutron matter and (Formula presented.) and lSNM = 0.48 fm−1 for symmetric nuclear matter.” Furthermore, the fourth sentence after Eq. (14) that reads “The correlation lengths learned from the training data are lme,PNM = 0.83 fm−1 for pure neutron matter and lme,SNM = 0.39 fm−1 for symmetric nuclear matter.” was changed from “The correlation lengths learned from the training data are lme,PNM = 0.81 fm−1 for pure neutron matter and lme,SNM = 0.34 fm−1 for symmetric nuclear matter.” Finally, the last sentence of the same paragraph now starts with “Here we simply used (Formula presented.) fm−1 (0.39 fm−1) as the correlation length …” which was changed from the original text “Here we simply used (Formula presented.) fm−1 (0.34 fm−1) as the correlation length …”. All results that involve predictions for properties of infinite nuclear matter have been corrected. Predictions for properties of finite nuclei, including the thickness of the neutron skin, are not affected. The original and corrected versions of Fig. 3, Extended Data Table 2 and Extended Data Figs. 6, 7b and 8a are shown in the Supplementary Information for this amendment, and the errors have been corrected in the HTML and PDF versions of the article. Supplementary Information is available in the online version of this amendment.
