Probing de Sitter Space Using CFT States: Constructing Bulk Local States in dS3/CFT2 and Analyzing Their Properties
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.

AdS/CFT Correspondence in the O(N) Invariant Critical φ⁴ Model: A Conformal Smearing Approach
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.

Holographic Duality for Boundary Conformal Field Theory with T¯T Deformation: Exploring the Interplay of Boundary Effects and Deformation
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.
Integrated Correlators and the AdS/CFT Correspondence in N=2 SYM Theories with Fundamental Flavors: A Matrix Model Approach
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.
