Summary: The study suggests that a holographic CFT with a boundary added to it does not usually have a 'good' holographic dual with a localized gravitating end-of-the-world brane, due to restrictive constraints imposed by bulk causal structure. This implies that even higher-dimensional holographic duals of BCFTs may not be generic.

Summary: We use holography to study the spectra of boundary conformal field theories. By considering the interactions between two circular boundaries, we obtain information about the operator content and energy spectrum of the dual BCFT. We first study the interaction between two highly separated boundaries mediated by a scalar field, which produces a light scalar primary and its descendants in the closed-string channel of the dual BCFT. We then consider a gravity model with point particles and find that non-smooth mergers of boundaries can describe boundary-condition-changing operators in the open-string spectrum of the BCFT. We also discover a new class of sub-threshold Euclidean bra-ket wormhole saddles with a factorization puzzle for closed-string amplitudes.

Summary: We construct a new family of AdS(2) x S-2 x S-2 solutions by applying non-Abelian T-duality on a recent class of solutions. A particular solution in this class is connected to an AdS5 Gaiotto-Maldacena geometry and has a line defect interpretation in the dual 4d N = 2 SCFT, which is studied in detail. This construction provides an example of the successful applications of non-Abelian T-duality to holography.

Summary: In this paper, we study various dynamical aspects of the AdS/BCFT correspondence in higher dimensions. By analyzing the metric perturbation in the gravity dual, we study the properties of the holographic stress energy tensor and calculate the stress energy tensor for a locally excited state on a half plane in a free scalar CFT. We also study the behavior of the scalar field perturbation in the AdS/BCFT setup and find complete reflections. Moreover, we provide support for the Island/BCFT correspondence in higher dimensions by comparing the entanglement entropy of a BCFT computed from the AdS/BCFT with that calculated from the Island formula. Finally, we show how one point functions in a BCFT can be calculated in our gravity dual.

Summary: In the large N limit, we compute the topologically twisted index of the 3d T[SU(N)] theory, utilizing recent results from five dimensional quiver gauge theories. Our calculation correctly reproduces the entropy of the universal black hole that can be embedded in the holographically dual solution.

Summary: In this paper, we investigate the dynamics of EOW branes in AdS using scalar fields, which provide a new gravity dual for CFTs on manifolds with boundaries. We find explicit solutions that correspond to boundary RG flows, as well as annulus-like or cone-like shaped EOW branes that require the presence of the scalar field. Moreover, we present a gravity dual for a CFT on a strip with different boundary conditions due to the scalar potential, resulting in a confinement/deconfinement-like transition depending on temperature and the scalar potential. Finally, we highlight the close relationship between this phase transition and the measurement-induced phase transition via a Wick rotation.

Summary: This work continues the study of one-loop partition function for higher derivative conformal higher spin fields in six dimensions and its holographic counterpart in seven dimensions. By considering specific boundary conditions and heat kernel coefficients, the authors were able to match UV and IR divergences and obtain independent anomaly coefficients. Further investigation into non Ricci-flat Einstein boundaries revealed a discrepancy in computations for spins higher than two.

Summary: We study spin-2 fluctuations in the type IIB theory on an infinite family of warped backgrounds AdS(2) x S-2 x T-4 x S-1 x I-rho with N = 4 supersymmetry. We find a special set of solutions, the minimal universal class, which is independent of the background data. These solutions correspond to operators with scaling dimension Delta = l + 1, where l is the quantum number of angular momentum on S-2. By computing the mode solutions, we determine the central charge of the dual field theories. We also discuss the relation between our results and the seed AdS(3) x S-2 x T-4 x I-rho backgrounds.

Summary: In this paper, we discuss ensemble averages of two-dimensional conformal field theories associated with an arbitrary indefinite lattice with integral quadratic form Q, and provide evidence that the holographic dual after the ensemble average is the three-dimensional Abelian Chern-Simons theory with kinetic term determined by Q. The resulting partition function can be written as a modular form expressed as a sum over the partition functions of Chern-Simons theories on lens spaces. For odd lattices, the dual bulk theory is a spin Chern-Simons theory, and several novel phenomena in this case are identified. The holographic duality prior to averaging is also discussed in terms of Maxwell-Chern-Simons theories.

Summary: We classify the necessary and sufficient conditions to obtain the near-horizon geometry of extremal supersymmetric rotating black holes embedded in 11d supergravity associated to rotating M2-branes. The conditions for supersymmetry are rewritten in terms of differential equations on an eight-dimensional balanced space using G-structure techniques. The geometry is constrained by a master equation reminiscent of the non-rotating case, and the asymptotically AdS(4) electrically charged Kerr-Newman black hole in 4d N = 2 supergravity is embedded in the classification. Additionally, the conditions for the near-horizon geometry of rotating black strings in Type IIB are presented using dualities with the 11d setup.

Summary: In this study, we examine the behavior of rigidly rotating and pulsating strings in the background of a 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory using the Neumann-Rosochatius (NR) model. By employing a generalized ansatz, we reduce the system to the one dimensional NR model in the presence of flux. The integrable construction of the model allows us to analyze the rotating and oscillating string solutions.

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.

Summary: In this study, conformal field theories on the real projective space RPd were analyzed, focusing on the two-point functions of scalar operators. Based on calculations of Witten diagrams on the quotient space AdS(d+1)/Z(2), an analytic approach to two-point functions was developed by converting the structure of conformal block decomposition into specific sum rules.

Summary: By utilizing 5-brane webs, we examined the two-dimensional space of supersymmetric mass deformations of higher rank generalizations of the 5d E-1 and E-1 theories. The analysis suggests that the number of different phases increases with the rank, and the space of deformations varies qualitatively for even and odd rank cases.

Summary: The thermal 2-point correlation functions in the black brane AdS(5) background dual to 4d CFT's at finite temperature for operators of large scaling dimension were computed. A formula matching the expected structure of the OPE was found, showing an exponentiation property whose origin was explained. Additionally, the first correction to the two-point function due to graviton emission, encoding the proper time from the event horizon to the black hole singularity, was computed.

Summary: Studying 2-point and 3-point functions in CFT at finite temperature for large dimension operators using holography provides insights into universal formulas for holographic free energy. By including alpha ' corrections, leading corrections at strong coupling can be reproduced. 3-point functions exhibit intricate structures and interesting properties, including a factorization property when dimensions satisfy specific conditions, suggesting that factorization in d > 2 is a reflection of the semiclassical regime.

Summary: In this study, 2-point correlation functions for scalar operators in position space are examined using holography, with a focus on operators with large conformal dimensions. The geodesic approximation is utilized for propagators. In addition to the main contribution, a correction involving bulk cubic couplings and higher curvature couplings is identified, which provides insight into the interior of a black hole.
