Holographic superconductivity of a critical Fermi surface

By Jörg Schmalian
We derive holographic superconductivity from a Hamiltonian that describes pairing of two-dimensional electrons near a ferromagnetic quantum-critical point. At low energies the theory maps onto a four-dimensional gravity description with Lifshitz spacetime and dynamic scaling exponent z=3/2z=3/2. The curved spacetime is due to powerlaw correlations of the critical normal state.... Show more
