Summary: In this study, WZW models living on a moduli space parameterized by current-current deformations were explored, revealing the ensemble of conformal field theories and their impact on conserved currents and central charge. The average partition function was calculated and interpreted as a sum over 3-manifolds, suggesting a holographic dual for the ensemble-averaged theory. At a perturbative level, the bulk theory was identified as U(1)(2N) Chern-Simons theory coupled to additional matter fields, with a key mathematical result being the Siegel-Weil formula for the characters of an affine Lie algebra.

Summary: We use the quantum spectral curve to compute the Hagedorn temperature for ABJM theory and obtain consistent results with known results for both weak and strong coupling. We numerically compute the dependence at strong coupling and find that it is consistent with expectations from supergravity and the plane-wave limit.

Summary: This article discusses the Cartan geometric approach to (extended) supergravity in the presence of boundaries, focusing on deriving the Holst variant of the MacDowell-Mansouri action for N = 1 and N = 2 pure AdS supergravity in D = 4 under arbitrary Barbero-Immirzi parameters. The close connection between the Barbero-Immirzi parameter and the theta-ambiguity of gauge theory is highlighted, along with the unique boundary term corresponding to a super Chern-Simons theory with OSp(N|2) gauge group when demanding supersymmetry invariance at the boundary.

Summary: The study focuses on the large-N limit of superconformal index for two strongly interacting Chern-Simons theories in three dimensions with N=2 supersymmetry, comparing the results with the AdS/CFT dual. The agreement and persistence of duality were confirmed, with a need for refinement of the gravity index in the case of mABJM to reflect enhanced global symmetry in the UV description on the field theory side.

Summary: The paper provides the most general solution to Chern-Simons AdS(3) gravity in Fefferman-Graham gauge and introduces a variational principle for Dirichlet boundary conditions in the Chern-Simons formalism. It demonstrates how to handle other choices of boundary conditions, such as mixed boundary conditions corresponding to a TT-deformation, using this variational principle as the starting point.

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: In this study, we apply the conjecture of gravitational building blocks to analyze M-theory on S-7/Z(k). By utilizing the known localization results for the holographically dual ABJM theory, we determine higher derivative corrections to the AdS(4) supergravity, quantum corrections, and predict ABJM observables using the uniquely fixed gravitational block.

Summary: In this work, the surface charges and associated algebra in T(T) over bar deformed theories are constructed using the Chern-Simons formalism of AdS(3) gravity from a mixed boundary condition perspective. The charge algebra is found to be a non-linear deformed Virasoro algebra, and a method is proposed to construct time-independent charges that satisfy the field-dependent Virasoro algebra.

Summary: In this paper, a Chern-Simons gravity dual of a two dimensional conformal field theory on a manifold with boundaries, known as boundary conformal field theory (BCFT), is provided. The correct boundary action on the end of the world brane in the Chern-Simons gauge theory is determined, reproducing known results of the AdS/BCFT for the Einstein gravity. A prescription for calculating holographic entanglement entropy using Wilson lines extending from the AdS boundary to the end of the world brane is given, and a higher spin extension of the formulation is discussed.

Summary: The study examines the thermodynamic contributions to the three-dimensional de Sitter horizon from metric and Chern-Simons gauge field fluctuations. In the Euclidean signature, these are calculated by the gravity partition function coupled to matter semi-classically expanded about the round three-sphere saddle. The Lorentzian picture and the gravitational edge-mode theory at the de Sitter horizon are explored, drawing inspiration from topological entanglement entropy literature.

Summary: This research focuses on the analytic continuations of holographic renormalization group (RG) flows beyond their infrared (IR) fixed points, which provide a natural framework for describing physics inside black holes. The study constructs a monotonic holographic a-function for counting degrees of freedom along a trans-IR flow. It is argued that the degrees of freedom become sparse and vanish when reaching a trans-IR endpoint represented by a Kasner singularity. Furthermore, the research demonstrates that entanglement and complexity from volume are generally insufficient in probing the trans-IR flows, while 2-point correlations and complexity from action are complementary and more effective in this regard.

Summary: This study discusses the holographic description of Narain U(1)(c) x U(1)(c) conformal field theories, proposing a hypothesis that the density of states of any Narain theory in the large central charge limit is bounded by the density of states of U(1) gravity. Testing this proposal using chiral lattice CFTs and CFTs based on quantum stabilizer codes reveals new bounds on quantum stabilizer codes and the exponentially small density variance in the central charge limit.

Summary: In this study, the Poincare series method was used to compute gravity partition functions for SU(N)(1) WZW models with varying modular invariants. The results showed an average over these invariants, with weights determined by inverting a matrix, which was specially formulated for the chosen models. It was found that for the identity seed, the weights were consistently positive for all values of N, indicating a dual relationship between each model and an ensemble average over CFT's.

Summary: In this study, we examine the superconformal index of 4d N = 4 USp(2N(c)) and SO(N-c) SYM from a matrix model perspective, focusing on the Cardy-like limit. We find that in both symplectic and orthogonal cases, the index is predominantly determined by a saddle point solution, leading to a matrix integral calculation involving pure Chern-Simons theory on the three-sphere. Additionally, we calculate the subleading logarithmic corrections and study the Leigh-Strassler fixed point with SU(N-c) gauge group, determining the entropy of the dual black hole through a Legendre transform.

Summary: The article reviews the properties of orbifold operations in two-dimensional quantum field theories and discusses the Orbifold groupoids that control the composition of orbifold operations. Three-dimensional TQFT's of Dijkgraaf-Witten type are highlighted for their important role in the analysis. The extension to generalized symmetries and applications to constrain RG flows is briefly discussed.

Summary: The objective of the large-scale cohort study was to provide updated information on the demographic, signs and symptoms, and imaging characteristics of COVID-19 patients in Wuhan, China. The study found that men and women were infected in roughly equal numbers, with fever and dry cough being the most common symptoms at disease onset. Patients with bilateral pneumonia and pleural effusion were more likely to develop respiratory failure or death.

Summary: This study found that COVID-19 survivors with dyspnea had significantly different characteristics compared to those without dyspnea. Parameters associated with lesion volume on CT scans showed the best predictive ability for post-discharge dyspnea among clinical and subjective CT findings. Lesion volume decreased gradually from peak period to discharge and continued to decrease 6 months after discharge.
