TLDR
The authors used mixed correlators in thermal CFT as clean probes of the strong gravity effects in their holographic duals and found an enhanced mixing at high temperatures, corresponding to large AdS black holes, concentrated to small boundary momenta, dual to the deep bulk, where strong gravitational fields are expected.Abstract:
We use mixed correlators in thermal CFT as clean probes of the strong gravity effects in their holographic duals. The dual interpretation of mixing is an inelastic conversion of one field to another field, induced by gravity: tidal excitation. We find an enhanced mixing at high temperatures, corresponding to large AdS black holes, concentrated to small boundary momenta, dual to the deep bulk, where strong gravitational fields are expected. We also find large $$ \mathcal{O}\left(1/{G}_N\right) $$
tidal conversion in the low temperature phase of the U(N) vector model, strengthening suspicions that the bulk dual of this phase also houses extremely compact objects.read more

Holographic thermal correlators revisited
TL;DR: In this article, a Witten diagram involving both the bulk cubic coupling and the higher curvature couplings is given, which is proportional to the VEV of a neutral operator and thus probes the interior of the black hole exactly as in the case studied by Grinberg and Maldacena.
Thermal Stress Tensor Correlators near Lightcone and Holography
TL;DR: In this paper , the authors consider thermal stress-tensor two-point functions in holographic theories in the near-lightcone regime and analyse them using the operator product expansion (OPE).

The Hagedorn - deconfinement phase transition in weakly coupled large N gauge theories
TL;DR: In this paper, it was shown that weakly coupled, large $N, d$-dimensional supersymmetric Yang-Mills theories on a class of compact spatial manifolds undergo deconfinement phase transitions at temperatures proportional to the inverse length scale of the manifold in question.

Massless higher spins and holography
Ergin Sezgin,Per Sundell +1 more
TL;DR: A survey of massless HS theories with 32 supersymmetries in D =4,5,7 (where the 7D results are new) is given and corresponding composite operators are discussed in this paper.

Correspondence principle for black holes and strings
TL;DR: In this article, the authors formulated a correspondence principle, which states that when the size of the horizon of a black hole decays below a given size of a string, the typical black hole state becomes a typical state of strings and D-branes with the same charges.

On the Gravitational Interaction of Massless Higher Spin Fields
E.S. Fradkin,Mikhail A. Vasiliev +1 more
TL;DR: In this article, it was shown that the gravitational interaction of massless higher-spin fields (s > 2) does exist at least in the first nontrivial order, despite a widespread belief.
