Description
When asymptotically AdS black holes are distorted, they can become unstable to a certain effect involving branes: we say that (in some cases) they are ``fragile''. The familiar planar black holes used in applications of AdS/CFT duality to heavy ion physics are fragile in this sense. In particular, if they are distorted by being given angular momentum and charge, they do become unstable. If we are using the black hole to describe a quark plasma with a large amount of internal angular momentum, such as might arise from certain peripheral collisions, then this effect would trigger a phase transition and could cut short the lifetime of the plasma. The effect varies across the quark matter phase diagram and might, *if* one believes in AdS/QCD, lead to observable phenomena as future facilities (such as FAIR) scan across that diagram.
