Publisher Correction: Two-dimensional Kβ-Kα fluorescence spectrum by nonlinear resonant inelastic X-ray scattering

Correction to: Nature Communications 10.1038/s41467-023-39967-4, published online 17 July 2023

The original version of this Article contained an error in Equation (2) and used incorrect size of the absolute value symbol.

The correct form of Equation (2) is:

$$\frac{d^2{\sigma }_{\mathrm{RIXS}}\left({\omega }_1,{\omega }_2\right)}{d\hslash {\omega }_{2}d{\mathrm{\Omega }}_2}=m^2{r}_0^2\left(\frac{{\omega }_2}{{\omega }_1}\right)\sum _f{∣\sum _n\frac{{\omega }_{fn}{\omega }_{ni}⟨f∣\widehat{r}∣n⟩⟨n∣\widehat{r}∣i⟩}{\hslash {\omega }_1-\hslash {\omega }_{ni}-i{\mathrm{\Gamma }}_n/2}∣}^2\times \delta \left(\hslash {\omega }_1-\hslash {\omega }_2-\hslash {\omega }_{fi}\right),$$

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