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. This effective theory determines
the low energy dynamics, stability and thermodynamic properties. Tools from flux
compactifications are also used to construct holographic CFTs with no relevant scalar
operators, that can lead to symmetric phases of condensed matter systems stable to
very low temperatures. The general formalism is illustrated with simple examples such
as toroidal compactifications and manifolds with a single size modulus. We initiate
the classification of holographic phases of matter described by flux compactifications,
which include generalized Reissner-Nordstrom branes, nonsupersymmetric AdS2 x R2
and hyperscaling violating solutions.
