Stress Tensor Deformations in dS/CFT: Mixed Boundary Conditions, Spectrum Flow and Pseudo Entropy
Feng Hao, Hao Ouyang, Xi-Yang Ran
We formulate a semiclassical stress tensor deformation dictionary in the context of the dS/CFT correspondence. Using the metric-flow formulation, we propose that stress tensor defo…
Relative Rényi Entropy Under Local Quenches in 2D CFTs
Zi-Xuan Zhao, Song He, Hao Ouyang +2
We study the relative Rényi entropy (RRE) under local quenches in two-dimensional conformal field theories (CFTs), focusing on rational CFTs (RCFTs) and holographic CFTs. In RCFTs…
Holography for stress-energy tensor flows
Xi-Yang Ran, Feng Hao, Hao Ouyang
We study the holographic description for general stress-energy tensor deformations in arbitrary dimensions using the metric flow approach. Mixed boundary conditions corresponding t…
Generalized -like flows for scalar theories in two dimensions
H. Babaei-Aghbolagh, Song He, Hao Ouyang
We demonstrate that the necessary condition for duality invariance manifests as a partial differential equation in two-dimensional scalar theories. This condit…
Generalized -like Deformations in Duality-Invariant Nonlinear Electrodynamic Theories
H. Babaei-Aghbolagh, Song He, Hao Ouyang
This study introduces a high-order perturbation methodology to categorize two primary solution types within duality-invariant nonlinear electrodynamic theories, adhering to the dif…
Deformation: Introduction and Some Recent Advances
Song He, Yi Li, Hao Ouyang +1
This review explores recent advances in the theory of deformation, an irrelevant yet solvable deformation of quantum field theories defined via the quadratic form of the…
