Integer dual dimensions in scale-separated AdS3 from massive IIA

A bstract We study supersymmetric scale-separated AdS 3 flux vacua of massive IIA on G2 orbifolds with smeared orientifold planes. We consider two types of $$ {T}^7/{Z}_2^3 $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mi>T</mml:mi> <mml:mn>7</mml:mn> </mml:msup> <mml:mo>/</mml:mo> <mml:msubsup> <mml:mi>Z</mml:mi> <mml:mn>2</mml:mn> <mml:mn>3</mml:mn> </mml:msubsup> </mml:math> orbifolds which, with appropriate flux choices, yield integer dual dimensions for the operators corresponding to the closed string scalar fields in the dual CFT. As with all other known examples, the dual conformal dimensions are only parametrically close to integer values.
