We consider a 1+1 dimensional Strange Metal, which arises from SU(N) gauge theory coupled to a multiplet of massive Dirac fermions transforming in the adjoint representation of the gauge group. The only global symmetry of this theory is a U(1) associated with the conserved Dirac fermion number, and we study the theory at variable, nonzero densities. The high density limit is characterized by a deconfined Fermi surface. Its low energy fluctuations are described by a coset conformal field theory with central charge c=(N^2-1)/3 and an emergent N=(2,2) supersymmetry. We determine the exact scaling dimensions of the operators associated with Friedel oscillations and pairing correlations. We discuss aspects of the N→∞ limit, and its possible dual description in AdS3 involving string theory or higher-spin gauge theory.
