R-Charge Chemical Potential in the M2-M5 System

Abstract: (arXiv)
We study probe M5 branes in M2 brane AdS_4 and AdS_4 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 M5 branes. The resulting M5 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.- potential: chemical
