“…Therefore it is not too far-fetched to consider Hořava-Lifshitz theory as a gravitational dual to some field theories [22]. Second, it is possible that Hořava-Lifshitz gravity can be formulated in a string-theoretic way, or string theory may be modified to include Lorentz breaking [23] [24]. Furthermore, as commented by Andrew Strominger et al in [25], any consistent theory of gravity should behave a lot like string theory.…”

The anti-de Sitter/conformal field theory (AdS/CFT) correspondence is a powerful tool that promises to provide new insights toward a full understanding of field theories under extreme conditions, including but not limited to quark-gluon plasma, Fermi liquid and superconductor. In many such applications, one typically models the field theory with asymptotically AdS black holes.These black holes are subjected to stringy effects that might render them unstable. Hořava-Lifshitz gravity, in which space and time undergo different transformations, has attracted attentions due to its power-counting renormalizability. In terms of AdS/CFT correspondence, Hořava-Lifshitz black holes might be useful to model holographic superconductors with Lifshitz scaling symmetry. It is thus interesting to study the stringy stability of Hořava-Lifshitz black holes in the context of AdS/CFT. We find that uncharged topological black holes in λ = 1 Hořava-Lifshitz theory are nonperturbatively stable, unlike their counterparts in Einstein gravity, with the possible exceptions of negatively curved black holes with detailed balance parameter ǫ close to unity. Sufficiently charged flat black holes for ǫ close to unity, and sufficiently charged positively curved black holes with ǫ close to zero, are also unstable. The implication to the Hořava-Lifshitz holographic superconductor is discussed.
