Contribution

It introduces new non-supersymmetric AdS4 solutions on coset manifolds and studies their stability and moduli spectrum.

Findings

Most vacua are stable under fluctuations

Most vacua lack massless moduli

New families of non-supersymmetric solutions are identified

Abstract

We construct new families of non-supersymmetric sourceless type IIA AdS4 vacua on those coset manifolds that also admit supersymmetric solutions. We investigate the spectrum of left-invariant modes and find that most, but not all, of the vacua are stable under these fluctuations. Generically, there are also no massless moduli.
