Description

We propose the first examples of scale-separated vacua with extended supersymmetry. They
arise as circle compactifications of four-dimensional vacua of massive type IIA supergravity
with scale separation, upon introducing additional fluxes and sources. We provide both the
ten-dimensional solutions and the three-dimensional effective descriptions in terms of Kähler
potential and superpotential. The conformal dimensions of the putative dual two-dimensional
field theory appear not to be integers. The superpotential for the additional fluxes of one of
our models was guessed by ChatGPT and, to the best of our knowledge, it does not appear in
existing literature. Should these vacua be solutions of string theory, they would allow to address
the open problem of scale separation from the vantage point of extended supersymmetry.
