Black branes in flux compactifications

Understand

We construct charged black branes in type IIA flux compactifications that are dual to (2+1)-dimensional field theories at finite density.

• The internal space is a general Calabi-Yau manifold with fluxes, with internal dimensions much smaller than the AdS radius.
• Gauge fields descend from the 3-form RR potential evaluated on harmonic forms of the Calabi-Yau, and Kaluza-Klein modes decouple.
• Black branes are described by a four-dimensional effective field theory that includes only a few light fields and is valid over a parametrically large range of scales.
