Title | Bad Metals, Density Waves and Black Holes |
Abstract | So-called 'bad metals' present a long-standing conundrum to theory. In particular, their electric resistivity is too high to be accounted for by weakly coupled quasiparticles as in conventional metals. In this talk, I will argue that ac and dc transport in the bad metallic regime can be explained by a long wavelength description of fluctuating charge density waves. Both ac and dc transport are governed by Planckian dynamics, which suggests that quantum fluctuations play an important role. I'll conclude by mentioning how gauge/gravity duality can be used to efficiently calculate conductivities in the quantum critical regime. |
