TL;DR
This paper constructs new non-supersymmetric solutions in D=7 gauged supergravity with AdS factors, which can be uplifted to D=11 supergravity, expanding the landscape of known M-theory backgrounds.
Contribution
It introduces a class of non-supersymmetric AdS solutions in D=7 supergravity that can be uplifted to eleven dimensions, involving warped and twisted products with Einstein manifolds.
Findings
Solutions include AdS2, AdS3, AdS4, and AdS5 factors.
Solutions can be uplifted to D=11 supergravity.
Some stability aspects are discussed.
Abstract
Solutions of D=7 maximal gauged supergravity are constructed with metrics that are a product of a n-dimensional anti-de Sitter (AdS) space, with n=2,3,4,5, and certain Einstein manifolds. The gauge fields have the same form as in the recently constructed solutions describing the near-horizon limits of M5-branes wrapping supersymmetric cycles. The new solutions do not preserve any supersymmetry and can be uplifted to obtain new solutions of D=11 supergravity, which are warped and twisted products of the D=7 metric with a squashed four-sphere. Some aspects of the stability of the solutions are discussed.
