Abstract
Multiparametric families of nonsupersymmetric EAdS4 flows as well as asymptotically EAdS4 solitons and wormholes are constructed within the four-dimensional SO(8) gauged supergravity that describes the compactification of M-theory on S7. More concretely, the solutions are found within the so-called STU model that describes the U(1)4 invariant sector of the theory. The on-shell action and gravitational free energy are computed for the regular solutions, the latter being zero for the wormholes irrespective of supersymmetry. There are special loci in parameter space yielding solutions with enhanced (super)symmetry. Examples include a supersymmetric EAdS4 flow with SO(4)×SO(4) symmetry dual to a specific real mass deformation of ABJM on S3 as well as a nonsupersymmetric wormhole with SU(3)×U(1)2 symmetry. Uplift formulas for these and other examples to Euclidean solutions of 11-dimensional supergravity are presented and their complex nature discussed. Published by the American Physical Society 2024
