Holographic duals of D=3 N=4 superconformal field theories

We find the warped AdS(4) x K type-IIB supergravity solutions holographically dual to a large family of three dimensional N = 4 superconformal field theories labeled by a pair (rho, (rho) over cap) of partitions of N. These superconformal theories arise as renormalization group fixed points of three dimensional mirror symmetric quiver gauge theories, denoted by T-(rho) over cap(rho)(SU(N)) and T-rho((rho) over cap)(SU(N)) respectively. We give a supergravity derivation of the conjectured field theory constraints that must be satisfied in order for these gauge theories to flow to a non-trivial supersymmetric fixed point in the infrared. The exotic global symmetries of these superconformal field theories are precisely realized in our explicit supergravity description.
