Exact Relevant Stress-Tensor Flows and a Causality No-Go in Self-Dual Electrodynamics
H. Babaei-Aghbolagh, Bin Chen, Song He +1
Can a classically relevant stress-tensor deformation be exactly solvable, duality preserving, and physically causal? We construct an exact power-law family of nonlinear electrodyna…
The Triple -Like Flow in Quantum Field Theories: Irrelevant, Marginal, and Relevant
H. Babaei-Aghbolagh, Bin Chen, Song He +1
We introduce a one-parameter root--like flow, , which organizes stress-tensor deformations into irrelevant, marginal, and re…
Geometric entropy and time-like entanglement entropy on a rotating BTZ black hole
Huayu Dai, Xi-Hao Fang, Mitsutoshi Fujita +1
In this paper, we analyze the double Wick rotation of a rotating BTZ black hole and the entanglement entropy. We derive the transition matrix dual to the double Wick-rotated BTZ bl…
Correlators in and Root- Deformed CFTs
Bo-Rui Li, Song He, Yu-Xiao Liu
Quasi-primary correlators in two-dimensional conformal field theories deformed simultaneously by and root- are studied. A path-integral formulation motivated by…
Classifying Causal Nonlinear Electrodynamics via -Parity and Irrelevant Deformations
H. Babaei-Aghbolagh, Komeil Babaei Velni, Song He +1
We investigate the classification of self-dual nonlinear electrodynamic (NED) theories based on their analyticity properties, which are directly linked to invariance under a discre…
A Unified Causal Framework for Nonlinear Electrodynamics Black Hole from Courant-Hilbert Approach: Thermodynamics and Singularity
H. Babaei-Aghbolagh, Komeil Babaei Velni, Song He +1
We develop a unified framework for analyzing black hole thermodynamics and spacetime structure in Einstein gravity coupled to causal nonlinear electrodynamics (NED) in asymptotical…
