We numerically construct asymptotically AdS black brane solutions of D = 4 Einstein theory coupled to a scalar and two U(1) gauge fields. The solutions are holographically dual to d = 3 CFTs in a constant external magnetic field along one of the U(1)’s. Below a critical temperature the system’s magnetisation density becomes inhomogeneous, leading to spontaneous formation of current density waves. We find that the transition can be of second order and that the solutions which minimise the free energy locally in the parameter space of solutions have averaged stressed tensor of a perfect fluid.
