| The Chiral Magnetic Effect (CME) is a phenomenon in which, a chiral chemical potential in an external magnetic field lead to an electric current along the magnetic field. This phenomenon has been observed in systems containing quark-gluon plasma and recently in systems concerned with condensed matter physics. Interactions in these systems are strong. Therefore, the best approach to analyzing this phenomenon is gauge/gravity duality which is a good tool for studying systems with strong interactions. Since, Lorentz symmetry does not existed in some condensed matter models, here, the chiral magnetic effect in non-relativistic systems is studied by introducing a suitable gravitational dualism. We will see Lorentz symmetry is broken and non-relativistic z=2 Schrodinger symmetry appears which is realized by Anti-de-Sitter-Schwarzschild black hole. In our Holographic model, system’s properties are in a good agreement with the experimental result of strange metals at very low temperature. What is really important is that, the chiral electric current in our model for a non-relativistic system which is dual to strange metal is half of what is obtained in relativistic Anti-de-Sitter space-time before. |
