Summary: In this study, six-point string amplitudes for the scattering of different states in D-brane-anti-D-brane systems in Type II superstring theories were computed, and the precise form and numerical coefficients of the couplings were derived, modifying and completing previous proposals. The study confirmed that the effective field theory reproduced the stringy gauge field singularities in dual channels. Additionally, a proposal for tensionless limits of D-brane-anti-D-brane systems was made based on interesting similarities between all-order highly symmetric EFTs and holographic duals of Vasiliev's higher spin gravities.

Summary: This research presents a topological construction of duality defects in quantum field theories, extending to lower supersymmetry cases. The QFTs of interest are realized through D3-branes probing a Calabi-Yau threefold cone with an isolated singularity, where the duality group descends to dualities of the 4D worldvolume theory. Different realizations of duality defects correspond to distinct choices of branch cut placements in the 5D bulk.

Summary: In this paper, expressions for refined open topological string partition function on certain non-compact Calabi Yau 3-folds with topological branes wrapped on special lagrangian submanifolds are proposed. The conjectures equate these open topological string partition functions with the generating function of equivariant indices on certain quiver moduli spaces. The identification of topological string partition functions with equivariant indices on the instanton moduli spaces is used to obtain these conjectures.

Summary: This study makes a significant advancement at the intersection of number theory and group theory by revealing the relationship between the order of a finite group and the dimension of its irreducible complex representation. Through finite algorithms, integer ratios between these quantities can be constructible combinatorially. These ratios are linked to the eigenvalues of handle creation operators, providing important implications in string amplitudes and topological field theories.

Summary: This paper focuses on studying entanglement entropy and edge modes in the A model topological string theory, presenting the concept of generalized entropy and gauge-string duality. By analyzing the topological closed string theory on the resolved conifold, the study reveals the existence of string edge modes and their interpretation as entanglement branes. The duality between the closed string theory and Chern-Simons gauge theory is explored, showing a mapping between the Hartle-Hawking state and a state containing Wilson loops.

Summary: In this study, the BPS spectra of D-branes on local Calabi-Yau threefolds were explored using nonabelianization for exponential networks to calculate unframed BPS indices. By computing new types of BPS invariants of 3d-5d BPS states, known results on these BPS spectra were accurately reproduced through wall-crossing. Additionally, the notion of exponential BPS graphs was developed for the simplest toric examples, showing their encoding of quiver and potential associated to the Calabi-Yau through geometric engineering.

Summary: This paper studies supersymmetric AdS(5) x Sigma solutions in seven-dimensional N = 2 gauged supergravity. The authors find solutions with nontrivial U(1) holonomy at the boundary or half-spindle, and identify their residual symmetry. They also discover solutions that can be used to describe four-dimensional N = 1 superconformal field theories and can be embedded in higher dimensions.

Summary: This paper investigates 5-brane web diagrams in 5D Sp(N) gauge theories and computes Nekrasov partition functions using the refined topological vertex formalism. The results are consistent with known results obtained from other methods, and a specific tuning of Kahler parameters associated with Higgsing is also discussed.

Summary: The study focuses on the impact of bulk perturbations of N=(2) superconformal minimal models on topological defects, identifying symmetries and general topological defects that persist through the flow to the IR. The method involves considering the topological subsector and utilizing the Landau-Ginzburg formulation to describe RG flows and topological defects in terms of matrix factorizations.

Summary: This study proposes a method for constructing new 5D N = 1 gauge models based on Sasaki-Einstein manifolds. These models extend the standard 5D models and have unitary SU(p)(q) gauge symmetries. Special attention is given to building gauge families with symplectic SP(2r, R) symmetry. The research in this paper is important for understanding the embedding of super quantum field theories and M-theory.

Summary: We propose quantum gravitational constraints on effective four-dimensional theories with N = 1 supersymmetry. These constraints arise from the Completeness Conjecture of quantum gravity and impose bounds on the axionic couplings and gauge sector rank in the theory. Concrete string theoretic settings are used to test and further motivate these bounds. The article also provides a detailed derivation of the EFT string constraints in heterotic string compactifications and applies these bounds to M-theory compactifications on G(2) manifolds.

Summary: The study investigates strings in N=2 supersymmetric U(1)(N) gauge theories with N hypermultiplets, considering arbitrary Fayet-Iliopoulos parameters and an invertible charge matrix. It is found that the Bogomol'nyi-Prasad-Sommerfield solutions have a tension linear in magnetic fluxes, which are related to winding numbers. The research establishes three types of solutions for the constraint equations, and it is shown that seemingly vanishing Bogomol'nyi bounds cannot have solutions. Additionally, the most general vortex equations are derived, showing an Abelian appearance after solving the constraint equations.

Summary: This study focuses on confinement in 4d N = 1 theories obtained by deforming 4d N = 2 theories of Class S. The researchers argue that confinement in a vacuum of the N = 1 theory can be encoded in the 1-cycles of the associated N = 1 curve. They reproduce the expected properties of confinement in classic examples and provide tools for probing confinement in non-Lagrangian N = 1 theories.

Summary: In this study, higher dimensional hairy black holes in quartic quasi-topological gravity are analyzed using non-abelian power-Yang-Mills theory. The existence of real solutions is shown to depend on the quartic quasi-topological coefficient being positive. Depending on various parameters, the solutions can represent black holes with different numbers of horizons and a naked singularity. Thermodynamic properties and conservation quantities are calculated, and the stability of the solutions is examined in different ensembles. New power-Yang-Mills hairy black hole solutions in pure quasi-topological gravity are also formulated and discussed. The thermodynamics of horizon flat power-Yang-Mills rotating black branes are analyzed as well.

Summary: The phase space of general relativity in a finite subregion is characterized by edge modes localized at the codimension-2 boundary, transforming under an infinite-dimensional group of symmetries. The quantization of this symmetry algebra is conjectured to be an important aspect of quantum gravity. A further infinite family of Casimirs can be constructed from the curvature of the normal bundle of the boundary surface. These arise as invariants of the little group, which is the group of area-preserving diffeomorphisms, and are the analogues of spin.

Summary: Progress in understanding the bulk microstate interpretation of the Ryu-Takayanagi formula requires defining entanglement entropy in closed string theory, which remains poorly understood in string theory. As a toy model for AdS/CFT, the study explores closed string entanglement entropy in the topological A-model under Gopakumar-Vafa duality, presenting results in two separate papers. The research also incorporates TQFT methods to factorize the closed string Hilbert space on the resolved conifold, revealing string edge modes transforming under a q-deformed surface symmetry group and relating nonlocal aspects to recent findings in JT gravity.
