Summary: We investigate the combined effect of fluxes and higher-order curvature corrections on the existence of de Sitter vacua in a heterotic string inspired framework. By studying a perturbative expansion in the small Gauss-Bonnet coupling, we gain intuition on the effects of these corrections. We show that, for choices of potential closer to the string theory predictions, the inclusion of quadratic curvature corrections reduces the parametric likelihood of de Sitter solutions.

Summary: In this study, we investigate the BPS submodels of the higher dimensional Skyrme model and their properties. Two possible BPS submodels, the BPS Skyrme model and the scale-invariant model, are found. The first submodel supports BPS Skyrmions with B >= 1, while the second submodel only has B = 1 BPS Skyrmion. The scale-invariant model exhibits a stronger self-duality condition compared to the BPS Skyrme model.

Summary: This study presents a detailed realization of the quantum field theory ensembles in D < 4 spacetime dimensions, allowing for a random averaging of coupling constants. The resulting volume, when each member of the ensemble is a conformal field theory with a standard semiclassical holographic dual, can be interpreted as an asymptotically anti-de Sitter space geometry with a distribution of boundary components joined by wormhole configurations. This construction provides a UV completion of the proposal for a high-dimensional Hilbert space for baby universes, while remaining consistent with the proposed swampland constraints.

Summary: By analyzing the interactions in ten-dimensional supergravity involving D7-branes and anti-D3-branes, it was shown that the equations of motion require the four-dimensional curvature to precisely match the values determined by the four-dimensional effective theory.

Summary: This study investigates the potential presence of generalized global symmetries in large classes of Type IIB four-dimensional N = 2 effective field theories, and explores how they are avoided. The research finds that the presence of generalized theta-terms plays an important role in breaking a large subset of the global symmetries, while the spectrum of charged states is constituted by an infinitely populated lattice due to the presence of these terms.

Summary: In this note, the mass spectrum of type IIB flux compactifications is studied. The mass matrix for F-term vacua in four-dimensional N = 1 supergravity theories is discussed in general, and then specialized to type IIB Calabi-Yau orientifold compactifications with geometric and non-geometric fluxes. In this setting, F-term vacua are generally AdS4 vacua, and the conformal dimensions of operators dual to the scalar fields are computed. One-loop corrections to the complex-structure moduli space lead to real-valued conformal dimensions for the mirror-dual of the DGKT construction, while non-integer conformal dimensions are obtained for a more general flux configuration than the DGKT mirror. It is also argued that stabilizing the axio-dilaton and complex-structure moduli in asymptotic regions of moduli space by fluxes implies that at least one of the corresponding mass eigenvalues diverges.

Summary: This study determines the higher symmetries of 5D SCFTs engineered from M-theory on a C3/r background and resolves the extraction of data when the resulting singularity is nontoric or not isolated. The BPS states of the theory are encoded in a 1D quiver quantum mechanics gauge theory and can also be extracted by computing the defect group associated with the orbifold singularity. The abelianization of r detects a 2-group structure when the geometry captures the global 0-form symmetry accurately.

Summary: Building on previous work, this paper presents an efficient algorithm for computing topological intersection numbers of divisors in a broad class of elliptic fibrations. The algorithm utilizes a symbolic computing tool and organizes the intersection products of divisors into a succinct analytic generating function. The implementation of the algorithm shows a significant reduction in computation time compared to previous methods.

Summary: In this paper, we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy. We showed that the ratio of Fourier-transforms of the symmetry resolved entanglement entropies takes a simple and universal form for these states. We also extended our results to excited states of interacting theories and developed a higher dimensional generalisation of the branch point twist field picture.

Summary: The research reveals that in the holographic SU(2) p-wave superconductor model with Weyl corrections, the conductivity in the superconducting phase exhibits obvious anisotropic behaviors. In the superconducting phase, a behavior similar to a Drude peak emerges in the real part of the conductivity, regardless of the behaviors in the normal state.

Summary: We study six-dimensional SU(n) gauge theories compactified on a two-dimensional torus with a constant magnetic flux background and provide a comprehensive low-energy mass spectrum. We consider general background configurations including the magnetic flux and continuous Wilson line phases, and derive the complete mass spectrum without imposing restrictions on the gauge fixing parameter. Our analysis reveals the presence of tachyonic modes that are independent of the background configurations and gauge fixing parameter. We also discuss the implications of stabilizing or condensing these tachyonic states in terms of phenomenology and the potential for constructing beyond the standard model scenarios.

Summary: We study minimal type-A higher-spin gravity in four dimensions, proposing new diagrammatic rules that involve Fronsdal fields and Didenko-Vasiliev particles. These rules can reproduce all n-point functions of the theory's holographic dual, the free O(N) vector model.

Summary: This study combines machine learning and algebraic geometry techniques to analyze line bundle cohomologies on families of holomorphic curves. By generating a large amount of data and training a model to provide intuition for cohomology jumps, the researchers construct additional vector-like Higgs pairs in an F-Theory toy model. Further tools from algebraic geometry, particularly Brill-Noether theory, are needed to quantitatively explain the entire dataset. A diagrammatic approach is introduced to express cohomology jumps across the parameter space of each family of matter curves, reflecting a stratification of the F-theory complex structure moduli space in terms of the vector-like spectrum.

Summary: The article discusses the combination of the Distance Conjecture and the Tameness Conjecture, proposing a method to divide the region near the infinite distance point into finite sectors to establish path-independent statements for the associated towers of states. Additionally, a more constrained class of tame functions is introduced to describe known string theory effective actions. It is found that the multi-field dependence of these functions can be reconstructed by one-dimensional linear test paths in each sector.

Summary: This article investigates the higher-spin gravity in (A)dS4 space, which is defined as the holographic dual of a free O(N) or Sp(N) vector model. The theory is considered non-local at distances greater than the (A)dS radius due to a mismatch in the massless exchange terms. However, the study shows that in the Euclidean OPE limit, there are no massless exchange-type non-localities for any spin, suggesting that the higher-spin theory is local in spacetimes with Euclidean boundary signature. This implies locality in de Sitter space for Lorentzian bulk.
