  We study probe D5 branes in D3 brane AdS_5 and AdS_5-Schwarzschild
backgrounds as a prototype dual description of strongly coupled 2+1 dimensional
quasi-particles. We introduce a chemical potential for a weakly gauged U(1)
subgroup of the theory's global R-symmetry by spinning the D5 branes. The
resulting D5 embeddings are complicated by the existence of a region of the
space in which the local speed of light falls below the rotation speed. We find
regular embeddings through this region and show that the system does not
exhibit the spontaneous symmetry breaking that would be needed for a
superconductor.
