We examine models of fermions with infinite-range interactions that realize non-Fermi liquids with a continuously variable U(1) charge density Q and a nonzero entropy density S at vanishing temperature. Real-time correlators of operators carrying U(1) charge q at a low temperature T are characterized by a Q -dependent frequency ω S = ( q T / ? ) ( ? S / ? Q ) , which determines a spectral asymmetry. We show that the correlators match precisely with those of the two-dimensional anti–de Sitter ( AdS 2 ) horizons of extremal charged black holes. On the black hole side, the matching employs S as the Bekenstein-Hawking entropy density and the laws of black hole thermodynamics that relate ( ? S / ? Q ) / ( 2 π ) to the electric field strength in AdS 2 . The fermion model entropy is computed using the microscopic degrees of freedom of a UV complete theory without supersymmetry.
