  A model of 3+1 dimensional gravity with negative cosmological constant
coupled to abelian gauge fields has been proposed as a gravity dual for
Lifshitz like critical phenomena in 2+1 dimensions. The finite temperature
behavior is described by black holes that are asymptotic to the Lifshitz fixed
point geometry. There is a one-parameter family of charged black holes, where
the magnitude of the charge is uniquely determined by the black hole area.
These black holes are thermodynamically stable and become extremal in the limit
of vanishing size. The theory also has a discrete spectrum of localized objects
described by non-singular spacetime geometries. The finite temperature behavior
of Wilson loops is reminiscent of strongly coupled gauge theories in 3+1
dimensions, including screening at large distances.
