Boundary flow and geometric realization in holographic -deformed BCFT
Feiyu Deng
We study the deformation of boundary conformal field theories (BCFTs) from an intrinsic field-theoretic perspective. Formulating the deformation as a modification of the…
Causality Criteria for Island Models
Feiyu Deng
Island models offer a compelling resolution of the black hole information paradox, but they also raise persistent questions about causal consistency in effective descriptions. In p…
An Interpretation for the Equivalence of Two Holographic Computations of the Butterfly Velocity with the Canonical Formalism of Gravity
Feiyu Deng, Xiao-Shuai Wang, Jie-qiang Wu
In this paper, we revisit the equivalence of two holographic computations of the butterfly velocity: the computation with the shock wave solution and the computation with the entan…
Holographic boundary conformal field theory with deformation
Zhi Wang, Feiyu Deng
We propose a holographic dual of boundary conformal field theory (BCFT) with deformation, i.e. of BCFT. Our holographic proposal distinguishes two types of $T\b…
