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

Abstract

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 magneto-transport for general QCP and discuss the special point $(z,\theta)=(3/2,1)$, where the data of Dirac material have previously been well described.
