Summary: In Dp-brane holography, entanglement in the target space of the D-brane Yang-Mills theory offers a precise notion of bulk entanglement in the gravity dual. The discussion expands by introducing a gauge invariant characterization of operator sub-algebras corresponding to such entanglement. Additionally, motivation is provided for why these operator sub-algebras are suitable for describing measurements carried out with low-energy probes in the bulk region of interest.

Summary: We argue that a type IIB Euclidean supergravity solution belongs to a chain of AdS x S x T vacua with self-dual flux. These vacua come from the near-horizon of specific branes and have supersymmetry for odd values of dimension. For the matrix model dual, the hallmark of conformal symmetry is a vanishing free energy when the dimension is 1. The corresponding supergravity solution indeed has vanishing on-shell action and specific fluxes need to be switched on.

Summary: We study minimum area surfaces associated with a region, R, of an internal space. We find that the result of Graham and Karch can be avoided in the presence of warping, and such surfaces can sometimes exist for a general region R. When such a warped product geometry arises in the IR from a higher dimensional asymptotic AdS, we argue that the area of the surface can be related to the entropy arising from entanglement of internal degrees of freedom of the boundary theory. We also make some preliminary observations about the role such surfaces can play in bulk reconstruction, and their relation to subalgebras of observables in the boundary theory.

Summary: This paper constructs gravity duals to supersymmetric gauge theories in the presence of unquenched flavor hypermultiplets. By considering the intersection of two sets of D3-branes in (1+1)-dimensional defect, the closed set of equations describing the dual geometry for a large number of colors and flavors in the Veneziano limit is derived. The solutions for massless flavors and the small flavor limit of massive hypermultiplets are briefly discussed. It is found that the 1/16-BPS supergravity solutions are generally asymptotically anti de-Sitter and the dilaton does not vary with the holographic radial coordinate, indicating the reliability of the classical Type IIB supergravity solutions for the gauge theories from the deep IR to the far UV.

Summary: In this study, the steady-state velocity of expanding vacuum bubbles nucleated within chiral finite temperature first-order phase transitions in strongly coupled large N QCD-like models is determined using holographic correspondence as a tool. The friction force exerted by the plasma on the bubbles and the steady-state velocity are calculated. The phase transitions are related to changes in the embedding of flavor branes probing the black hole background in a top-down holographic description.

Summary: In this study, we constructed a black hole geometry dual to a (2+1)-dimensional defect in an ambient (3+1)-dimensional gauge theory. By exciting a gauge field in the worldvolume of the dynamic brane sources, we generated quark density and investigated the thermodynamics of the black hole as well as the energy density and pressures of the dual theory.

Summary: The introduction of electric field in the D-brane worldvolume leads to the formation of a horizon in the open string geometry perceived by brane fluctuations. The holographic entanglement entropy (HEE) and subregion complexity (HSC) in these asymptotically AdS geometries have been studied in three, four, and five dimensions to capture the effects introduced by the D-branes in the flavor sector. Results show that the Bekenstein-Hawking entropy associated with the open string horizon now precisely matches with the entanglement entropy at high temperatures, after earlier failures in reproducing the thermal entropy in the boundary. Validity of the embedding function theorem was checked while computing the HEE, and attempts were made to reproduce the first law of entanglement thermodynamics, at least at leading order, based on the obtained results.

Summary: A new infinite family of Type IIB backgrounds with an AdS(2) factor is presented, each with a proposed dual Super Conformal Quantum Mechanics (SCQM) model. Holographic expressions for the number of vacua, Chern-Simons terms, and other non-perturbative aspects of the SCQM are provided. The central charge of the one-dimensional system is related to a combination of electric and magnetic fluxes in Type IIB, with an extremisation principle proposed using Ramond-Ramond fluxes. Other physical and geometrical aspects of these conformal quantum mechanics are analyzed.

Summary: This paper studies B-brane superpotentials that depend on several closed- and open-moduli on Calabi-Yau hypersurfaces and complete intersections. By blowing up the ambient space along a curve wrapped by B-branes in a Calabi-Yau manifold, a new manifold and the period integral satisfying the GKZ-system are obtained. Using mirror symmetry to the A-model, the superpotentials and Ooguri-Vafa invariants are calculated for specific examples of several open-closed moduli in Calabi-Yau manifolds.

Summary: This study investigates the target space entanglement entropy in a complex matrix model, which describes the chiral primary sector in N=4 super Yang-Mills theory. The distribution of eigenvalues in the model corresponds to a boundary condition in the bubbling AdS geometry. The study calculates the target space entanglement entropy and the area of the boundary of a subregion, and finds a qualitative agreement between them.

Summary: In the context of low-scale gravity and large extra-dimensions, we demonstrate that the discrepancy between the measured anomalous magnetic moment at BNL and Fermilab, and the Standard Model prediction, can be explained. The dominant contribution to (g - 2)(mu) comes from Kaluza-Klein excitations which do not mix with quarks and can be light enough to avoid LHC constraints. The KK tower provides a distinct signal that will be observable with future muon smashers.

Summary: This study focuses on 4N = 1 gauge theories engineered via D-branes at orientifolds of toric singularities, where gauge anomalies are cancelled without the introduction of non-compact flavor branes. By using dimer model techniques, the researchers derive geometric criteria for determining whether a given singularity can admit anomaly-free D-brane configurations based on its toric data and orientifold projection type. These results extend the connection between geometric properties of singularities and physical properties of corresponding gauge theories.

Summary: The study revisits D3-branes at toric CY3 singularities with orientifolds and their description through dimer models. New orientifold projections related to maps on the dimer without fixed points, leading to Klein bottles, were classified through smooth involutions of the torus. These new orientifolds lead to novel N = 1 SCFT's resembling non-orientifolded theories, including the presence of fractional branes and triggering cascading RG-flow like Klebanov-Strassler. The remaining involutions lead to non-supersymmetric setups, covering all possible orientifolds on dimers.

Summary: This paper presents the first instance of a D-brane model at Calabi-Yau singularities where supersymmetry is broken dynamically into stable vacua. The model demonstrates the same low energy effective dynamics and opens up the possibility of smooth geometrical effects describing the gauge theory throughout the RG flow, including the deep IR, in terms of a weakly coupled gravity dual background. The relevance of this result in the wider context of the string landscape and the Swampland program is also discussed.

Summary: Non-invertible symmetries have been extensively studied in quantum field theories in recent years, and this note explores their study in supergravity. The authors discover infinite families of non-invertible defects in 11d and 10d Type II supergravities. These operators have a diverse impact on different probe branes. The authors also discuss how these symmetries are eliminated in the UV completion and their connection to the absence of global symmetries in Quantum Gravity and the Completeness Hypothesis.

Summary: We demonstrate that simple theories of abelian gauge fields with a cubic Chern-Simons term in 5d possess an infinite number of non-invertible codimension two defects. These defects are created by modifying the symmetry operators of the broken electric 1-form symmetry with a suitable topological field theory, at any rational angle. We also examine these theories within the presence of a 4d boundary, particularly in a holographic setting. In this scenario, we observe that the bulk defects can have various outcomes when pushed to the boundary, including the formation of codimension one non-invertible defects in a boundary theory with an ABJ anomaly.
