Summary: This study examines the asymptotic behavior of the (modified) superconformal index for 4d N = 1 gauge theory, finding that the 'high-temperature limit' of the index can be expressed in terms of conformal anomalies. Moreover, the macroscopic entropy of the interacting SCFT system is derived from the asymptotic free energy when certain bounds are satisfied. Additionally, the Carby limit of the index for N = 1 theories dual to AdS(5) x Y-p,Y-p is found to explain the Bekenstein-Hawking entropy of large black holes.

Summary: In this study, the correlation functions of Wilson (-'t Hooft) loops with chiral primary operators in the N = 4 supersymmetric Yang-Mills theory with S O(N) gauge symmetry were computed. The holographic dual description of this theory is the Type IIB superstring theory on the AdS(5) x RP5 background. The coefficients of the chiral primary operators in the operator product expansion of Wilson loops in different representations were computed and compared with those of the N = 4 SU(N) super Yang-Mills theory.

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: 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: 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: The large-N asymptotics of the topologically twisted index of N = 4 SU(N) Super-Yang-Mills (SYM) theory on T-2 x S-2 is investigated and interpreted holographically based on the black hole Farey tail. The regularized on-shell actions of a family of 5d extremal solutions uplifted from the 3d black hole Farey tail are computed in a dual N = 2 gauged STU model to compare with a canonical partition function derived from the twisted index in the large-N limit, improving holographic understanding of the twisted index.

Summary: We study the Cardy-like limit of the superconformal index for generic N = 1 SCFTs, providing strong evidence for a universal formula that captures the behavior of the index at finite order in rank and angular momentum fugacities. Our proposal is validated by studying several examples beyond the well-understood toric class. Additionally, we compute the index for models without a weakly-coupled gravity dual, with gravitational anomalies not of order one.

Summary: In this study, we examine the superconformal index of 4d N = 4 USp(2N(c)) and SO(N-c) SYM from a matrix model perspective, focusing on the Cardy-like limit. We find that in both symplectic and orthogonal cases, the index is predominantly determined by a saddle point solution, leading to a matrix integral calculation involving pure Chern-Simons theory on the three-sphere. Additionally, we calculate the subleading logarithmic corrections and study the Leigh-Strassler fixed point with SU(N-c) gauge group, determining the entropy of the dual black hole through a Legendre transform.

Summary: The study focuses on various sub-leading structures in the superconformal index of N = 4 supersymmetric Yang-Mills theory with SU(N) gauge group, utilizing saddle-point approximation and Bethe-Ansatz approach to find perfect agreement, including a logarithmic correction of log N. Generalizing these methods to cover 4d N = 1 superconformal theories reveals consistent approximations across different scenarios.

Summary: The study investigates the Bethe-Ansatz approach to superconformal index of N = 4 supersymmetric Yang-Mills theory with SU(N) gauge group, revealing that while standard solutions fully recover the index for N = 2, they are insufficient for N >= 3 due to the challenging role played by the continuous families of non-standard solutions.

Summary: In this study, subleading corrections to the genus-zero free energy of the N=3 Gaiotto-Tomasiello theory are investigated. The endpoints and free energy are obtained as a set of parametric equations via contour integrals of the planar resolvent, up to exponentially suppressed corrections. Furthermore, an explicit (perturbative) expansion for the free energy is found in the case where the two gauge groups in the quiver are of equal rank, with the full expression for the genus-zero free energy obtained if both groups have equal levels, modulo exponentially suppressed corrections. Numerical verification of the results is also performed.

Summary: The study focuses on the S-3 x S-1 superconformal index I(tau) of 4d N = 1 gauge theories, with an asymptotic expansion revealing the coefficients of different terms and the growth of the 4d index being governed by background Chern-Simons couplings. This expansion provides insight into the behavior of the index as q approaches a root of unity, shedding light on the underlying mechanisms of the system.

Summary: The sub-leading structures of the free energy in N = 3 Chern-Simons-matter quiver gauge theories with gauge group U(N)(r) (r >= 2) were investigated using saddle point approximation and ideal Fermi-gas model for computing the partition function. A comparison of the resulting expressions for the free energy suggested a potential universal 1/6 log N correction. The study also indicated a connection between the sub-leading correction of the planar free energy in the large 't Hooft parameter limit and higher-derivative corrections to the tree-level holographic dual free energy in massive Type IIA theory.

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: In this study, constraints on four-derivative corrections to 5d Einstein-Maxwell theory from the black hole weak gravity conjecture (WGC) are analyzed. The research calculates the leading corrections to the extremal mass of asymptotically flat 5d charged solutions as well as 4d Kaluza-Klein compactifications. The analysis shows that the WGC bounds on 4d dyonic black holes are found to be strictly stronger, leading to new constraints on purely gravitational theories.
