TL;DR: In this article, the light-front wave function for the valence quark state of mesons using the AdS/CFT correspondence has been considered, as has been suggested by Brodsky and Teramond.
Abstract: We consider the light-front wave function for the valence quark state of mesons using the AdS/CFT correspondence, as has been suggested by Brodsky and Teramond. Two kinds of wave functions, obtained in different holographic Soft-Wall models, are discussed.

TL;DR: In this paper, the gravity dual to a class of three-dimensional N = 2 supersymmetric gauge theories on a biaxially squashed three-sphere, with a non-trivial background gauge field, is described by a 1/2 BPS Euclidean solution of four-dimensional n = 2 gauged supergravity, consisting of a Taub-NUT-AdS metric with an instanton for the graviphoton field, and the holographic free energy of this solution agrees precisely with the large N limit of the localized partition function

TL;DR: In this article, the authors apply the quantum extremal surface construction to calculate the Page curve of the eternal Reissner-Nordstrom black holes in four dimensions ignoring the backreaction and the greybody factor.
Abstract: We apply the recently proposed quantum extremal surface construction to calculate the Page curve of the eternal Reissner-Nordstrom black holes in four dimensions ignoring the backreaction and the greybody factor. Without the island, the entropy of Hawking radiation grows linearly with time, which results in the information paradox for the eternal black holes. By extremizing the generalized entropy that allows the contributions from the island, we find that the island extends to the outside the horizon of the Reissner-Nordstrom black hole. When taking the effect of the islands into account, it is shown that the entanglement entropy of Hawking radiation at late times for a given region far from the black hole horizon reproduces the Bekenstein-Hawking entropy of the Reissner-Nordstrom black hole with an additional term representing the effect of the matter fields. The result is consistent with the finiteness of the entanglement entropy for the radiation from an eternal black hole. This facilitates to address the black hole information paradox issue in the current case under the above-mentioned approximations.

TL;DR: A generalization of the Britto-Cachazo-Feng-Witten recursion relations gives a new and efficient method of computing correlation functions of the stress tensor or conserved currents in conformal field theories with an (d+1)-dimensional anti-de Sitter space dual in the limit where the bulk theory is approximated by tree-level Yang-Mills theory or gravity.
Abstract: We show that a generalization of the Britto-Cachazo-Feng-Witten recursion relations gives a new and efficient method of computing correlation functions of the stress tensor or conserved currents in conformal field theories with an ($d+1$)-dimensional anti--de Sitter space dual, for $d\ensuremath{\ge}4$, in the limit where the bulk theory is approximated by tree-level Yang-Mills theory or gravity. In supersymmetric theories, additional correlators of operators that live in the same multiplet as a conserved current or stress tensor can be computed by these means.

TL;DR: In this article, an infinite family of semi-classical AdS2 geometries can contribute effects of order exp(S 0/c), where S 0 is the Bekenstein-Hawking-Wald entropy and c is an integer greater than one.
Abstract: We study exponentially suppressed contributions to the degeneracies of extremal black holes. Within Sen's quantum entropy function framework and focusing on extremal black holes with an intermediate AdS3 region, we identify an infinite family of semi-classical AdS2 geometries which can contribute effects of order exp(S0/c), where S0 is the Bekenstein-Hawking-Wald entropy and c is an integer greater than one. These solutions lift to the extremal limit of the SL(2,) family of BTZ black holes familiar from the ``black hole Farey tail". We test this understanding in = 4 string vacua, where exact dyon degeneracies are known to be given by Fourier coefficients of Siegel modular forms. We relate the sum over poles in the Siegel upper half plane to the Farey tail expansion, and derive a ``Farey tale" expansion for the dyon partition function. Mathematically, this provides a (formal) lift from Hilbert modular forms to Siegel modular forms with a pole at the diagonal divisor.
