The original version of this Article contained an error in Fig. 2, in which the vertical energy axes of panels b and d were scaled by 122% relative to panels a and c instead of the 130% stated in the caption. This figure has been corrected in both the PDF and HTML versions of the article.

The original version of this Article contained an error in the fifth sentence of the section ‘Raman scattering result’, which incorrectly read ‘Near-optimal do**, 2ΔSC is known to be about 86 meV (ref. 18, compared to 93 meV in our sample) for Hg1201.’ The correct version states ‘ref. 30’ in place of ‘ref. 18’. This has been corrected in both the PDF and HTML versions of the Article.

The original version of this article contained an error in the fourth from the last sentence of the section ‘Analysis of RIXS spectra’ of the Methods, which incorrectly read ‘This result is generally consistent with previous RIXS results for doped cuprates, e.g., in ref. 40.’ The correct version states ‘ref. 8’ in place of ‘ref. 40’. This has been corrected in both the PDF and HTML versions of the Article.

The original version of this article contained an error in Eq. (5), which incorrectly read:

$$\omega (H)=2J\sqrt{\frac{1-{(\cos (2\pi H)+1)}^{2}}{4}}.$$

The correct form of Eq. (5) is:

$$\omega (H)=2J\sqrt{1-\frac{{(\cos (2\pi H)+1)}^{2}}{4}}.$$

This has been corrected in the PDF and HTML versions of the article.

The original version of the Supplementary Information associated with this article contained errors in the reference numbers. The HTML has been updated to include a corrected version of the Supplementary Information.
