Findings

Supergravity solutions with backreacted flavor branes are obtained.

The models describe unquenched flavor effects in low-dimensional gauge theories.

The solutions involve branes wrapping cycles in Calabi-Yau threefolds.

Abstract

We obtain gravity duals to supersymmetric gauge theories in two and three spacetime dimensions with unquenched flavor. The supergravity solutions are generated by a set of color branes wrapping a compact cycle in a Calabi-Yau threefold, together with another set of flavor branes extended along the directions orthogonal to the cycle wrapped by the color branes. We construct supergravity backgrounds which include the backreaction induced by a smeared set of flavor branes, which act as delocalized dynamical sources of the different supergravity fields.
