Multiply charged magnetic black branes

We discuss analytic solutions describing magnetically charged black branes in $d$ dimensional AdS space. Focusing on $d=5$, we study the response of the brane to an external short lived electric field. We argue that when the theory possesses an 't Hooft anomaly then at sufficiently low temperature a long lived oscillatory current will be observed long after the electric field has been turned off. We demonstrate this ``anomalous resonance'' effect via a numerical study.
