Abstract
Supersymmetric and non-supersymmetric deformations of large N = (4, 4) SCFT with superconformal symmetry D 1(2, 1; α) × D 1(2, 1; α) are explored in the gravity dual described by a Chern-Simons N = 8, (SO(4) × SO(4)) ⋉ T12 gauged supergravity in three dimensions. For α > 0, the gauged supergravity describes an effective theory of the maximal supergravity in nine dimensions on AdS 3 × S 3 × S 3 with the parameter α being the ratio of the two S 3 radii. We consider the scalar manifold of the supergravity theory of the form SO(8, 8)/SO(8) × SO(8) and find a number of stable non-supersymmetric AdS 3 critical points for some values of α. These correspond to non-supersymmetric IR fixed points of the UV N = (4, 4) SCFT dual to the maximally supersymmetric critical point. We study the associated RG flow solutions interpolating between these fixed points and the UV N = (4, 4) SCFT. Possible supersymmetric flows to non-conformal field theories and half-supersymmetric domain walls within this gauged supergravity are also investigated.
