Extending the scope of holographic mutual information and chaotic behavior

We extend the use of holography to investigate the scrambling properties of various physical systems. specifically, we consider: (i) non-conformal backgrounds of black dp branes, (ii) asymptotically lifshitz black holes, and (iii) black ads solutions of gauss-bonnet gravity. we use the disruption of the entanglement entropy as a probe of the chaotic features of such systems. our analysis shows that these theories share the same type of behavior as conformal theories as they undergo chaos; however, in the case of gauss-bonnet gravity, we find a stark difference in the evolution of the mutual information for negative gauss-bonnet coupling. this signal an inconsistency of the latter.
