This paper explores the holographic duality between three-dimensional de Sitter space (dS3) and two-dimensional conformal field theory (CFT2) by constructing CFT states that represent local excitations in dS3, called bulk local states. The authors find that the conjugation operation in dS3/CFT2 differs significantly from AdS3/CFT2, requiring a CPT-invariant combination of two bulk local states to obtain physical states. This difference explains the emergence of a time coordinate from the Euclidean CFT and allows for the derivation of the correct two-point function in the dS Euclidean vacuum.

This paper presents a novel geometric approach to understanding the flat limit of the AdS/CFT correspondence by analyzing the behavior of geodesics in AdS spacetime, demonstrating how this perspective provides insights into constructing flat space scattering amplitudes and explaining the antipodal matching of Liénard-Wiechert fields.
This paper explores the landscape of connected AdS3 solutions in type IIB and heterotic supergravities, revealing a 17-parameter family of solutions that includes TsT deformations and Wilson loops, and discusses their properties, stability, and holographic interpretations.
This paper investigates the emergence of the AdS/CFT correspondence in the O(N) invariant critical φ⁴ model in 3-dimensions using a novel technique called conformal smearing. The authors demonstrate that the bulk geometry, derived from the information metric, corresponds to an asymptotic AdS space at both UV and IR limits, reflecting the fixed points of the boundary theory. Notably, the bulk-to-boundary propagator accurately encodes the conformal dimension of the composite scalar operator at both fixed points, highlighting the successful mapping of boundary field theory dynamics to the bulk.
本文探討了在 $T\bar T$ 形變下邊界共形場論 (BCFT) 的全息對偶,並根據形變是否影響邊界將其分為兩種类型,並分別計算了邊界熵、能量譜、糾纏熵和 Rényi 熵等物理量來支持這一對偶關係。
This research paper proposes a holographic dual model for boundary conformal field theory (BCFT) with T¯T deformation, categorized into two types based on whether the boundary is deformed by the T¯T operator, and provides evidence for the duality by calculating entanglement entropy, boundary entropy, and energy spectrum.
This paper investigates the integrated correlators of moment-map operators in the D theory, an N=2 superconformal gauge theory, using a matrix model approach based on supersymmetric localization. By studying the mass-deformed D theory (D* theory) and analyzing its free energy at strong coupling, the authors aim to constrain the scattering amplitudes of gluons in the holographic dual theory described by Type IIB string theory on AdS5 x S5/Γ.
This paper investigates the self-dual sectors of Yang-Mills theory and Einstein gravity in Anti-de Sitter space (AdS4), revealing a simplified structure for their boundary correlators and soft limits, hinting at a potential double copy structure and connections to asymptotic symmetries.
This paper proposes a novel method to compute non-planar corrections to operator dimensions in ABJM theory at strong coupling by leveraging the theory's duality to M-theory and employing semiclassical quantization of M2 branes wrapped on an internal circle in AdS4 × S7/Zk.
