Correction to: Communications Physics https://doi.org/10.1038/s42005-022-00907-1, published online 01 June 2022.
It has come to the authors’ attention that equation [22] and [23] on page 6 of the published manuscript contained some notation mistakes.
The original equation [22] was written as
And has now been changed to
The original equation [23] was written as
and has now been corrected to
As a result of these changes the text has been modified as follow: (i) the second sentence of the paragraph below equation [22] has been changed from
“The instability threshold is reached when the curly brackets become zero, while the generation of the ±ν sideband pair is stable if the pump frequency is tuned to provide δ0b such that \({\delta }_{va}^{2} \; \leqslant \; {\delta }_{\mu a}^{2}.\)”to
“The instability threshold is reached when λν,μ becomes zero, while the generation of the ±ν sideband pair is stable if the pump frequency is tuned to provide δ0b such that \({\delta }_{va}^{2} \; \leqslant \; {\delta }_{\mu a}^{2}+\frac{1}{4}{\kappa }_{a}^{2}\)”.
(ii) the following text has been added immediately following equation [23] where \({\varepsilon}_{\!\pm}={\varepsilon }_{0}+{\kappa }_{a}^{2}/2{D}_{2a}(1\pm 2v).\)
In addition to the above, some omissions to the authorship of bibliographic references [13], [14], [15], were corrected. These references have been published with just the first author name appearing and were not reported in standard Nature referencing style as

Both the HTML and PDF version of the article have been corrected.
