Abstract：We perform a detailed analysis of a large class of effective holographic models with broken translations at finite charge density and magnetic field. We exhaustively discuss the dispersion relations of the hydrodynamic modes and successfully match them to the predictions from charged hydrodynamics. We compute the optical conductivities and the quasinormal modes and observe that the pinning frequency of the magneto-resonance peak increases with the magnetic field, revealing the quantum nature of the holographic pinning mechanism. We then study metal-insulator transition induced by the charge density, magnetic field and disorder from holography. Some universal scaling behavioris uncovered, in agreement with experimental observation on certain 2D materials.
