Supergravity realisations of $\hat{I}»$-models

Abstract

We construct solutions of type-II supergravity based on multiple copies and/or mixings of $\hat{I}»$-deformed coset CFTs on $\mathrm{SO}(n+1{)}_k/\mathrm{SO}(n{)}_k$, with $n=2,3,4$. The resulting ten-dimensional geometries contain undeformed $\mathrm{AdS}$ factors, thereby allowing a connection between $\hat{I}»$-deformations and the AdS/CFT correspondence. Imposing reality conditions on the solutions further constrains the deformation parameter. In some cases these bounds exclude the undeformed ($\hat{I}»=0$) or non-Abelian T-dual ($\hat{I}»\to 1$) limits. This work extends the results of 1911.12371 and 2411.11086.
