Holographic renormalization confirms quantum statistical relation for general rotating charged AdS black holes in five and six dimensions

The reading

This paper establishes that the holographically renormalized Euclidean on-shell action of the most general non-extremal rotating electrically charged AdS black holes in five-dimensional STU gauged supergravity and six-dimensional N=4 SU(2) gauged supergravity satisfies the quantum statistical relation (QSR) of black hole thermodynamics, up to a scheme-dependent Casimir term in odd dimensions and exactly in even dimensions. The key technical move is the use of the asymptotically global AdS frame, a specific radial coordinate in which the cutoff surface is the Einstein static universe $S^{1}$ x $S^{{d-2}}$ for all values of the black hole parameters. This frame makes the counterterms and the Casimir term universal constants, independent of the rotation and charge parameters, so that a single finite counterterm choice removes the Casimir offset in odd dimensions. The work also shows that background subtraction at a constant radial coordinate in the same frame fails to reproduce the QSR, and it identifies the mismatch exactly in terms of the reference action and the finite parts of the holographic counterterms. The results place holographic comparisons of black hole on-shell actions with dual field theory quantities (such as the superconformal index) on a first-principles footing, without relying on the QSR imported from Lorentzian thermodynamics.

What carries the argument

The asymptotically global AdS frame, defined by a coordinate transformation (2.28) from the Boyer-Lindquist-type coordinates to coordinates (τ, ~r, ~μ_i, φ_i) in which the metric asymptotes to global Euclidean AdS_d (2.30) with boundary $S^{1}$ × $S^{{d-2}}$. In this frame the induced metric on the radial cutoff surface is the Einstein static universe for all values of the black hole parameters, making the Casimir energy and the finite counterterms universal constants. The holographic renormalization procedure (2.26) then consists of the bulk on-shell action (2.21)/(2.77), the Gibbons-Hawking-York term (2.22), and the counterterms (2.24) built from the induced metric and the superpotential.

Extended reading notes

Core claim

The paper demonstrates that for the general non-extremal rotating electrically charged AdS5 black hole of the STU model and the AdS6 black hole of N=4 SU(2) gauged supergravity, holographic renormalization performed in the asymptotically global AdS frame yields a renormalized Euclidean on-shell action that satisfies the quantum statistical relation (QSR) of black hole thermodynamics. In five dimensions the relation holds up to a parameter-independent Casimir term that can be removed by a single finite counterterm; in six dimensions it holds exactly with no scheme ambiguity. This is the first direct evaluation of the holographically renormalized on-shell action for these general black holes, confirming that the Euclidean saddle alone suffices for precision holography without importing Lorentzian thermodynamic data via the QSR. The paper also shows that background subtraction in the same frame fails to reproduce the QSR, and it provides an exact decomposition of the mismatch in terms of the renormalized on-shell action of the reference background and the finite parts of the holographic counterterms.

Load-bearing premise

The entire analysis assumes that the asymptotically global AdS frame, defined by the coordinate transformation (2.28), is the correct and universal frame for holographic renormalization of these black holes. The paper acknowledges that holographic renormalization is not yet established for general asymptotically locally AdS black holes, and that the conformally flat boundary $S^{1}$ × $S^{{d-2}}$ is essential for the Casimir term to be a universal constant.

Editorial extensions

If this is right

  • Holographic comparisons of black hole on-shell actions with the large-N superconformal index — previously reliant on the QSR — are now placed on a first-principles footing, confirmed by direct evaluation of the Euclidean saddle.
  • The asymptotically global AdS frame provides a canonical radial coordinate for holographic renormalization of rotating charged AdS black holes with conformally flat boundaries, extending the known result from seven dimensions to five and six dimensions.
  • Background subtraction at constant ~r in the asymptotically global AdS frame is shown to be inadequate for precision holography; a criterion for the cutoff surface remains to be established for this method to be reliable.
  • The exact identification of the mismatch between holographic renormalization and background subtraction in terms of the reference action and counterterm finite parts provides a diagnostic for future work on background subtraction.
  • The results confirm that the Euclidean black saddle alone suffices for precision holography, without the need to import Lorentzian thermodynamic data via the QSR.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • The universality of the asymptotically global AdS frame for holographic renormalization suggests that the same frame should be the starting point for extending these results to black holes with non-conformally flat boundaries, such as those with squashed spheres or toroidal boundaries, where the logarithmic counterterms and finite counterterms will depend on the boundary data.
  • The failure of background subtraction at constant ~r in the asymptotically global AdS frame implies that the Hawking-Horowitz prescription of matching the induced fields on the cutoff surface to 'sufficient order' needs to be made precise; the relative order ~r^{3-d} at which the black hole deviates from the reference may provide a natural criterion.
  • The parameter-independent Casimir term in odd dimensions, removed by a single finite counterterm, suggests that the scheme ambiguity in odd-dimensional holographic renormalization can be resolved by requiring the QSR to hold, which fixes the finite counterterm uniquely.
  • The explicit evaluation of the on-shell action for the general AdS6 black hole provides a gravitational check of the entropy function proposal for AdS6 black holes, which was previously inferred from the QSR and the superconformal index.
Original abstract

We revisit the regularized on-shell actions of rotating electrically charged AdS black holes of gauged supergravity via holographic renormalization and background subtraction, with a particular emphasis on the frame in which the radial cutoff is placed. For holographic renormalization, the asymptotically global AdS frame, recently employed in seven dimensions, works equally well in five and six dimensions: the renormalized on-shell action of the AdS$_d$ black holes with $S^1\times S^{d-2}$ conformal boundaries satisfies the quantum statistical relation, up to a parameter-independent Casimir term in odd dimensions, and thereby places the holographic comparisons that so far relied on this relation on a first-principles footing. Background subtraction, in contrast, fails to reproduce this result in the same frame; the mismatch, which we identify exactly in terms of the Casimir term and the counterterms, demands a criterion for the cutoff surface yet to be established. For precision holography, our results settle the choice of frame for holographic renormalization with conformally flat boundaries and delineate the ambiguities that remain in background subtraction and in holographic renormalization for boundaries that are not conformally flat.
