The magnetic effect on a strongly correlated system with two currents near the quantum critical point from holography

Abstract

We study the magnetic effect in a strongly interacting system with two conserved currents near the quantum critical point (QCP). For this purpose, we introduce the hyper-scaling violation geometry with the black hole. Considering the perturbation near the background geometry, we compute the transport coefficients using holographic methods. We calculated the magnetotransport for general QCP and discuss the special point (z, theta) = (3/2, 1), where the data of Dirac material have previously been well described.
