Holography for an $\AdS_5$ to Hyperscaling-Violating Flow via Dimensional Reduction from 8d Einstein-Matter Gravity
Year: 2026
Type: preprint
Abstract: We construct a classical eight-dimensional Einstein--matter model whose reduction on a three-torus admits an $\AdS_5$ ultraviolet vacuum and a hyperscaling-violating infrared solution. Neutral scalar winding maintains the ultraviolet vacuum, while its disappearance allows the infrared geometry to become locally $\AdS_8$. The same reduction fixes the running gauge coupling, charged scalar mass and interactions. We derive the vacuum conditions, the radial evolution equations and the infrared spectrum. Scalar and vector superfluid orders are then compared using exact ultraviolet zero modes and analytic infrared eigenvalue identities. The scalar and vector instabilities in the infrared coincide at a unique scalar mass above the Breitenlohner--Freedman bound. Their nonlinear competition is governed by a quartic free energy that includes electric response and the change between fixed chemical potential and fixed density. For the interpolating geometry, we identify the conditions under which the two orders can appear together and form a locally stable phase.
