Summary: In the large N limit, we compute the topologically twisted index of the 3d T[SU(N)] theory, utilizing recent results from five dimensional quiver gauge theories. Our calculation correctly reproduces the entropy of the universal black hole that can be embedded in the holographically dual solution.

Summary: In this study, we discuss 3d T-rho(sigma)[SU(N)] quiver gauge theories with a large number of nodes and ranks scaling quadratically with the length of the quiver. The sphere free energies and topologically twisted indices were obtained using supersymmetric localization, showing quartic scaling with the length of the quiver and quadratic scaling with N. The IR SCFTs have supergravity duals in Type IIB, with free energies matching holographic results and previously discussed theories arising as limiting cases. Each balanced 3d quiver theory is linked to a 5d parent, with close relations between BPS observables dominated by the same saddle point in the matrix model.

Summary: In certain large N gauge theories, a large number of operators are found within a band of low conformal dimensions. For example, the four-dimensional N = 1 supersymmetric SU(N) gauge theory flows to a superconformal theory in the infrared upon a superpotential coupling with gauge singlets. The gap in the low-lying spectrum scales as 1/N and the central charges scale as O(N-1).

Summary: Researchers utilized recently developed tools from exceptional field theory to calculate the full Kaluza-Klein spectrum of the AdS5 Pilch-Warner solution in type IIB supergravity, providing detailed information about the spectrum of protected and unprotected operators in the four-dimensional N = 1 Leigh-Strassler SCFT through the AdS/CFT correspondence. They also explicitly calculated the superconformal index of the SCFT in this limit and demonstrated its precise agreement with the spectrum of protected operators in the supergravity calculation.

Summary: In this study, entanglement entropy of a spherical region in (3 + 1)-dimensional N = 4 supersymmetric SU(N) Yang-Mills theory was computed using holographic methods. It was found that the entanglement entropy monotonically decreases as the sphere's radius increases, which is consistent with certain theoretical expectations. The study also observed similar decreasing trends in the entanglement entropy of a symmetric-representation Wilson line screened in SU(N - 1), even though there is no established physical principle to explain this behavior.

Summary: It has been shown that the superconformal index of N=4 super-Yang Mills theory can be represented as a matrix integral. Recently, Murthy demonstrated that this integral can be expressed as a sum of terms corresponding to a giant graviton expansion of the index, and provided an explicit formula for a single giant graviton. In this study, similar explicit formulae are given for an arbitrary number of giant gravitons. Examples of 1/2 and 1/16 BPS indices are provided, and it is shown that the expansion of the matrix integral differs from the giant graviton expansion computed in the supergravity dual, indicating that the giant graviton expansion is not necessarily unique once two or more giant gravitons start appearing.

Summary: In d-dimensional CFTs with a large number of degrees of freedom, the thermalization of stress tensor and multi stress tensor operators is equivalent to a universal behavior of their OPE coefficients with a pair of identical heavy operators. In free CFTs, multi stress tensor operators thermalize while light operators do not.

Summary: We study the limit of the superconformal index of the ABJM theory on S-1 x S-2 with a small circle size compared to the sphere radius. We find closed form expressions for the leading terms in this limit, valid to all orders in the 1/N expansion. By rewriting the superconformal index, we establish a connection with the Bethe Ansatz Equations that govern the topologically twisted index. Applying the same technique, we extend these results to the superconformal index of 3d N = 4 SYM coupled to one adjoint and N-f fundamental hypermultiplets. The implications of our findings for holography and charged rotating black holes in AdS(4) are discussed.

Summary: This paper studies non-planar corrections in two specific N=2 superconformal SU(N) gauge theories that are planar-equivalent to N=4 SYM theory. The leading non- planar corrections are found to be given by a power series with rational coefficients. The observables in the two models are related in a simple way in the double scaling limit. These relations are valid only at strong coupling and not in the weak coupling regime. The paper also discusses a dual string theory interpretation of the leading corrections to the free energy.

Summary: In this study, we apply the localization technique to compute the free energy and the circular BPS Wilson loop in a four-dimensional N= superconformal Sp(2N) gauge theory. We find that to any order in large N expansion and an arbitrary 't Hooft coupling lambda, the free energy and the Wilson loop satisfy Toda lattice equations.

Summary: In this study, we compute the spin 2 spectrum associated with massive graviton fluctuations in a-y-deformed Gaiotto-Maldacena background. This spectrum is holographically dual to the marginal deformations of N = 2 SCFTs in four dimensions. By analytically estimating the spectra for both the-y-deformed Abelian T dual (ATD) and non-Abelian T dual (NATD) cases, we find a continuous spectra associated with the breaking of U(1) isometry in the presence of the-y deformation. We also discuss the effects of adding flavour branes and the nature of the associated spin 2 operators in the dual N = 1 SCFTs.

Summary: We propose a new approach to extract the physical consequences of S-duality of four-dimensional N = 4 super Yang-Mills (SYM) and its string theory dual using SL(2, Z) spectral theory. Our method can constrain the analytic structure of N = 4 SYM data and has implications for the structure of instantons. In large N limits, we derive the existence and scaling of non-perturbative effects. We also discuss the implications for holography and embedding ensemble averaging into the traditional AdS/CFT paradigm.

Summary: The use of supersymmetric localisation has led to modular covariant expressions for integrated correlators of half-BPS operators in N = 4 supersymmetric Yang-Mills theory with a general classical gauge group. Generating functions for such integrated correlators have been determined, confirming previously conjectured formulae. This provides a systematic understanding of the relation between properties of these correlators at finite N and their expansions at large N, including a non-perturbative completion of the large-N expansion in terms of non-holomorphic modular functions.

Summary: This study investigates logarithmic corrections to the entropy of supersymmetric, rotating, asymptotically AdS(5) black holes and black strings. It uses the AdS/CFT correspondence to determine the entropy on the field theory side. The results show perfect agreement between gravitational and field-theoretic methods, providing a window into precision microstate counting and demonstrating the efficacy of low-energy, symmetry-based approaches for asymptotically AdS black objects under certain conditions.

Summary: This paper investigates the long-range force between zero-temperature black holes in two-derivative theories of gravity coupled to matter. It is found that the presence of massless scalar fields and four-derivative corrections can break the no-force condition for these black holes. By calculating the higher-derivative corrections to the scalar charges, it is determined that the higher-derivative corrected black holes can be either self-attractive or self-repulsive, depending on the values of the Wilson coefficients and scalar moduli VEVs.

Summary: In this paper, we study the four-derivative corrections to pure N = 2, D = 5 gauged supergravity. We find a single four-derivative superinvariant that can be added to the action, up to factors of the two-derivative action, and this selects a unique set of coefficients for the four-derivative corrections. We confirm these coefficients on the BMPV solution in the ungauged limit.

Summary: This study investigates the approximate perturbative solutions of multi-centered BPS black holes in asymptotically AdS(4) space, describing their motion and supersymmetric properties. The results show that a single black hole preserves half of the supersymmetry, while a configuration of multiple black holes has only 1/4 supersymmetry.

Summary: In this study, we examine the superconformal index of three-dimensional N = 2 supersymmetric field theories computed via localization on S-1 x S-2. We develop a Cardy-like expansion where the ratio of S-1 radius to S-2 radius is very small. We highlight the sub-leading structures in this expansion and their interaction with the large-N limit for U(N) gauge group theories.

Summary: The study investigates the topologically twisted index of three-dimensional super-symmetric field theories on a specific geometric background and identifies a universal logarithmic correction. This correction translates into a one-loop effect on the dual supergravity theory, and its matching depends on a generic cohomological property of particular manifolds.
