Magneto-Transport of a Reissner-Nordstrom Holographic Metal

The AdS/CFT correspondence provides a way to perform computations on strongly interacting, conformal systems living in the AdS boundary by studying the behaviour of the holographic dual in the form of a black hole in the centre. Until now, such inquiries where limited to spatially homogeneous systems, however, metallic systems are characterized by the presence of an ionic lattice. We study the DC magneto-transport of a dual to Reissner-Nordstrom metal using a novel code which numerically computes its behaviour in two dimensions in the presence of an explicit lattice and a magnetic field. We find that conductivity is dominated by Drude transport at low temperatures. Furthermore, we find that the transport is described by a transverse relaxation rate of angular momentum in addition to a longitudinal rate and these depend differently on temperature. This hints that AdS/CMT may provide an explanation to the anomalous temperature scaling of the Hall Angle in the strange metal phase of...Show moreThe AdS/CFT correspondence provides a way to perform computations on strongly interacting, conformal systems living in the AdS boundary by studying the behaviour of the holographic dual in the form of a black hole in the centre.
