# Holographic non-Fermi Liquids

Playing this video requires the latest flash player from Adobe.

We describe a class of non-Fermi liquid systems, using the AdS/CFT correspondence. The Fermi surfaces are studied by computing the response functions of fermionic operators. The scaling behavior near the Fermi surfaces is determined by conformal dimensions in an emergent IR CFT. The low-energy excitations near the Fermi momenta are not Landau quasiparticles. When the operator is marginal in the IR CFT, the full spectral function is precisely of the marginal Fermi liquid' form, introduced as a phenomenological model of the strange metal' phase of high temperature superconductors.
