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: An analytic approach to the four-point crossing equation in CFT is developed for general spacetime dimension. The study identifies a useful basis for complex analytic functions in two variables, related to double-twist operators in mean field theory. The basis of functionals appears to be closely related to the CFT dispersion relation recently derived by Carmi and Caron-Huot.

Summary: This paper provides a unified treatment of dispersive sum rules for four-point correlators in conformal field theory. The different methods discussed in the paper can be mapped into one another, leading to completely equivalent sum rules. Non-negative sum rules are constructed above the double-twist gap.

Summary: We have found that inhomogeneous cost functions are unrelated to circuit complexity, while selecting metrics that provide the tightest possible lower bounds helps reduce the list of candidate complexity measures. Assigning infinite costs to directions not belonging to the gate set, among other methods, can reduce unnecessary calculations.

Summary: By defining circuits based on unitary representations of Lorentzian conformal field theory in 3 and 4 dimensions, we are able to generalize formulas for circuit complexity starting from spinning primary states. These results are effectively replicated through the geometry of coadjoint orbits of the conformal group. However, unlike the complexity geometry derived from scalar primary states, the geometry derived from spinning primary states is more intricate and the presence of conjugate points signaling complexity saturation is still unknown.

Summary: In this paper, we construct infinite new classes of AdS(4)× S(1)× S-5 solutions of type IIB string theory with non-trivial SL(2, Z) monodromy along the S-1 direction, which are supersymmetric and dual to N = 1 SCFTs in d = 3. These solutions arise as limiting cases of Janus solutions of d = 4, N = 4 SYM theory, supported by different values of coupling constant on each side of the interface, as well as by fermion and boson mass deformations.

Summary: The study explores momentum space dispersion formulas in general quantum field theories and their applications in conformal field theory correlation functions. By utilizing two independent methods, it is demonstrated that quantum field theory dispersion formulas can be represented using causal commutators, with key components at four points being the same causal double-commutators. The research further shows the equivalence between momentum space dispersion formulas and CFT dispersion formulas for four-point functions, along with the relationship between Polyakov-Regge expansions associated with them through a Fourier transform.

Summary: A set of structures appearing in the four-point function of protected operators in N = 4 super Yang-Mills with SU(N) gauge group was computed at any order in a large N expansion, determined solely by leading order CFT data. By focusing on a specific limit, a connection was made with the dual supergravity amplitude in flat space, where these structures correspond to iterated s-cuts. Several checks were performed and it was conjectured that the same interpretation holds for supergravity amplitudes on AdS(5) x S-5.

Summary: This paper explores perturbative corrections to quantum information geometry, focusing on the Bures information metric associated with correlation functions of a conformal field theory. The metric of holographic four-point functions is computed, with corrections generated by tree Witten diagrams in the bulk included. The properties of correlators are translated into the language of information geometry in this setting. The cross terms in the information metric encode non-identity operators in the operator product expansion (OPE), and it is found that the information metric is asymptotically AdS. Additionally, an information metric for transition amplitudes is discussed.

Summary: The study investigates the dynamics of various entanglement measures in quantum systems after exciting the ground state, revealing a close-knit structure among them that strongly depends on the chaoticity of the theory. Evidence is found for breakdown of the quasi-particle picture in 2D conformal field theories and universality of entanglement dynamics in non-equilibrium systems.

Summary: We revisit the proposal that the ensemble average over free boson CFTs in two dimensions is dual to an exotic theory of gravity in three dimensions dubbed U(1) gravity. Flavored partition functions, weighted by Wilson lines coupled to U(1) currents, fulfill a heat equation relating Riemann surface moduli deformations to chemical potential deformations. This leads to a Siegel-Weil formula that computes the average of these flavored partition functions.

Summary: This study investigates the mild form of the Weak Gravity Conjecture, which suggests that quantum or higher-derivative corrections affect the mass of large extremal black holes at fixed charge. By analyzing charged and rotating black holes, the validity of this condition is demonstrated. It also derives stronger positivity bounds on the five-dimensional Wilson coefficients compared to considering charged black holes alone.

Summary: The study presents an analysis pipeline utilizing persistent homology to characterize the topology of large scale structure and extract cosmological constraints. By examining the impact of primordial local non-Gaussianity on dark matter halo distribution through N-body simulations, they detected non-zero f(NL)(loc) on multiple cubic volumes. The method effectively addresses degeneracies between different topological signatures and provides interpretable statistics for both reproducing previous results and making new predictions.

Summary: The article discusses the implications of recent progress in understanding the black hole information paradox for complementarity in de Sitter space. It describes a bulk procedure that allows information expelled through the cosmological horizon to be received by an antipodal observer, relying crucially on selection of the Bunch-Davies vacuum state and the presence of an (entangled) energy reservoir.

Summary: This paper studies the complex saddles of 4D axion gravity and its dual description in terms of a 3-form flux. Transition amplitudes are computed using the Lorentzian path integral and Picard-Lefschetz theory, revealing a qualitative change in the number and nature of saddles when a bilocal operator is present. The stability of the Giddings-Strominger wormhole is also analyzed in the 3-form picture and found to be perturbatively stable, raising questions about its fate in a UV-complete theory of quantum gravity.

Summary: In this paper, the authors investigate if the mild form of the Weak Gravity Conjecture applies to extremal rotating black holes. They find that the sign of the corrections to the rotating extremality bounds is non-universal and argue that the presence of a superradiant instability is important for black hole decay.

Summary: Euclidean wormhole geometries sourced by axions and dilatons are puzzling objects in quantum gravity. The consistency of the solution may be affected by corrections from the UV, even when the wormholes are large. In this study, we provide the first explicit 10D lifts of regular Euclidean axion wormholes and find that they can be controlled under supergravity regime. We also construct explicit wormholes in AdS spaces and find them to be under parametric control.

Summary: This paper discovers a new scalar field in the open-string sector that allows for interpolation between different flux quanta in type IIA string theory. It is found that the limit of large fluxes is consistent with the distance conjecture and that the massive IIA vacua pass an important Swampland criterion. The analysis also suggests the possibility of flux vacua being connected through trajectories in open-string field space, rather than just singular domain walls.

Summary: This research applies modern methods in computational topology to discover and characterize phase transitions, utilizing persistent homology to compute topological features and persistence images to distinguish phases. By employing logistic regression on these images, relevant features such as magnetization, frustration, and vortex-antivortex structure are identified as key factors in phase transitions. This method also defines persistence critical exponents and explores their relationship with traditionally considered critical exponents.
