Instabilities of near-extremal black branes

Abstract: Extremal horizons (and associated emergent quantum criticality of the corresponding holographic models) receive strong quantum corrections at very low temperatures.  We point out that when such models are embedded in top-down holography, extremal horizons can suffer from classical instabilities way before quantum effects become important. We present detailed analysis of the perturbative stability of the
baryonic black branes (in type IIB supergravity) and baryonic black membranes (in M-theory).
