Summary: The article discusses the localization approach to N = 2 superconformal SU(N) x SU(N) quiver theory and the non-Gaussian two-matrix model representation of the BPS circular SU(N) Wilson loop W. The study focuses on the subleading 1/N-2 term in the large N expansion of W at weak and strong coupling, particularly in the case of symmetric quiver with equal gauge couplings. A string theory argument suggests that the 1/N-2 term in this orbifold theory should have similar strong coupling asymptotics as in the N = 4 SYM case, which is supported by numerical studies of the localization matrix model. Additionally, a relation between the 1/N-2 term in the Wilson loop expectation value and the derivative of the free energy of the orbifold gauge theory on a 4-sphere is found.

Summary: This study focuses on the half-BPS circular Wilson loop in N = 4 super Yang-Mills with an orthogonal gauge group, utilizing supersymmetric localization to compute its expectation value exactly. The research highlights the large N limit and tests the duality with type HB string theory in AdS(5) x RP5, demonstrating precise matching in the strong coupling limit of the Wilson loop expectation value with the classical action of the dual string theory object. Additionally, the D5-brane description is used to determine the leading strong coupling behavior of the bremsstrahlung function associated with a spinor probe charge, showing agreement with localization predictions.

Summary: This article studies the fate of reparametrization invariance of Wilson loops under the RG flow, using large-N, strongly coupled CFTs and the holographic dual description. The results show that a cutoff in the holographic radial direction breaks conformal invariance and induces an effective defect action at the cutoff scale.

Summary: This paper investigates the behavior of the defect CFT defined by the half-BPS Wilson loop in the large charge limit. Using holography, the authors compute 1/J corrections to the correlation function of heavy and light insertions and derive the scaling dimensions and structure constants for non-protected dCFT operators. They also find a close connection between their results and the semi-classical integrability of the string sigma model.

Summary: This study investigates the two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in N = 4 supersymmetric Yang-Mills theory on both sides of the AdS/CFT correspondence. By analyzing the holographic and field theory perspectives, the behavior and efficacy of the correlators are determined.

Summary: In this study, we focus on the large charge sector of the defect CFT defined by the half-BPS Wilson loop in planar N = 4 supersymmetric Yang-Mills theory. By investigating correlation functions of two large charge insertions and several light insertions, we obtain important results in the double-scaling limit. We also compute the two-point function of large charge insertions and generalize the boundary terms, providing results for non-extremal cases as well.

Summary: We study the integrability properties of Wilson loops in the N = 6 three-dimensional Chern-Simons-matter (ABJM) theory. We construct an open spin chain and compute the reflection matrices to analyze the interaction and anomalous dimensions of operators. We also propose a Y-system and BTBA equations to verify the properties of Wilson loops in the ABJM theory.

Summary: In this study, we investigate multipoint correlators of protected scalars on the Maldacena-Wilson line in N = 4 SYM. By working at weak coupling and using the planar limit, we derive an explicit recursion relation that captures next-to-leading order correlators with arbitrary number of insertions of the fundamental scalar field. Furthermore, we observe that all the correlators can be annihilated by a special class of differential operators.

Summary: We study Wilson loops in string theory realizations of AdS/BCFT and wedge holography. The holographic representation of antisymmetric Wilson loops associated with individual 3d gauge nodes in terms of probe D5-branes is identified. This identification provides a concrete notion of which parts of the 10d solutions correspond to the end-of-the-world brane and which to the remaining bulk. Supersymmetric Janus on the brane embeddings in AdS(5)xS(5), describing surface defects with boundaries and interfaces in N = 4 SYM, are also constructed.

Summary: The study focuses on multipoint correlators of scalar fields on the 1 d defect CFT, with a weak-coupling recursion relation introduced to capture correlators at next-to-leading order. Composite operator correlators can be built by pinching scalar fields together. Results for correlators containing up to six points are provided, along with an expansion using conformal blocks and verification of extracted CFT data.

Summary: In this study, the null hexagonal Wilson loop in 4D N = 4 Super Yang-Mills is interpreted using an ADHM-like instanton construction for the matrix part. Localization techniques are then applied to obtain combinatorial expressions in terms of Young diagrams, leading to explicit expressions in several specific cases with exact agreement to existing literature. Moreover, explicit determinations of the denominator and interesting recursion properties for the residues are found.

Summary: In this study, we investigate the two-point functions of single-trace half-BPS operators in the presence of a supersymmetric Wilson line in N = 4 SYM. Using modern analytic bootstrap and an inversion formula, we reconstruct the CFT data from a single discontinuity of the correlator. In the planar strong coupling limit, we obtain closed-form expressions for two-point functions of single-trace operators of various weights and confirm that they satisfy the expected properties.

Summary: This study investigates the holographic correlators corresponding to scattering of fluctuations of an open string worldsheet with AdS(2) geometry, and finds that in the out-of-time-order configuration, the correlators display a Lyapunov growth that saturates the chaos bound. By utilizing a double-scaling limit, the exact form of the out-of-time-order correlator (OTOC) can be obtained, which is found to have the same functional form as the analogous calculation in JT gravity.

Summary: The research investigates the localization representations of 1/2 BPS circular Wilson loop W in N = 4 SYM theory and calculates their 1/N expansions in the limit of large 't Hooft coupling lambda. It discovers properties related to string coupling and string tension, as well as the expansion forms of Wilson loops and correlators with chiral primary operators. Similar phenomena are found in the ABJM theory as well.

Summary: In this study, the expectation value of the circular BPS Wilson loop in N = 2 superconformal SU(N) gauge theory is investigated, with connections to AdS/CFT duality established through string theory path integrals and localization matrix model representations, confirming the lambda(3/2) scaling prediction. The research provides insights into the universal scaling behavior of non-planar corrections in large 't Hooft coupling regimes in the context of superstring theory dualities.

Summary: The study continues with the strong-coupling expansion of non-planar corrections in N = 2 4d superconformal models, focusing on theories with gauge groups SU(N) and Sp(2N). Exact differential relations between 1/N terms in the free energy and 1/2-BPS Wilson loop expectation value are found using the localization matrix model representation, with discussions on their large 't Hooft coupling expansions and dual string theory interpretation. Resummed expressions for leading strong coupling terms in the 1/N expansion are derived in the Sp(2N) case, along with the identification of exponentially suppressed contributions to non-planar corrections and comments on their resurgence properties.

Summary: In this study, we extend previous work and find the two-loop term in the beta-function for the scalar coupling in a generalized Wilson loop operator of the N = 4 SYM theory. We also predict the two-loop term in the anomalous dimension of the scalar field inserted on the standard Wilson loop. Additionally, we compute the two-point correlators of scalars inserted on the Wilson line.

Summary: The paper investigates the generalized Wilson loop operator in the N = 4 SYM theory, focusing on its beta function and Wilson loop expectation value. By generalizing previous results, the study considers arbitrary representations of the gauge group and goes beyond the planar limit. It is found that in a specific limit, the generalized Wilson loop reduces to a purely scalar line operator. The computation of the beta function and circular loop expectation value in this limit provides constraints on the structure of the beta function for general representations.

Summary: The paper investigates the strong 't Hooft coupling expansion in special four-dimensional N = 2 superconformal models that are planar-equivalent to N = 4 super Yang-Mills theory. By utilizing a Fredholm determinant of a Bessel operator and a generalized Szego-Akhiezer-Kac formula, the expansion of leading corrections to various observables is derived and it is shown that the resulting strong-coupling expansions suffer from Borel singularities.

Summary: This study considers a four dimensional U(N) N = 4 SYM theory interacting with a 3d N = 4 theory on a co dimension-one interface, which is holographically dual to the D3-D5 system without flux. Localization captures various observables in this dCFT, including the free energy, defect expectation value, and single trace 1/2-BPS composite scalars. These quantities can be computed in a hermitian one-matrix model with a non-polynomial single-trace potential. The integrable Volterra hierarchy underlying the matrix model is exploited to systematically study its 1/N expansion at any 't Hooft coupling.

Summary: This paper studies the Schur index of N = 4 U(N) SYM theory in 4d and its holographic giant graviton-type expansion at finite N. The world-volume brane superconformal index is computed using a recently proposed definition of the gauge holonomy integral as a multivariate residue. The brane expansion and its relation to previous giant graviton-type representations of the Schur index are clarified.
