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…
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…
Integrable Sigma Models and Universal Root Deformation via Courant-Hilbert Approach
H. Babaei-Aghbolagh, Bin Chen, Song He
We develop a unified Courant--Hilbert framework for constructing two-dimensional integrable sigma models deformed by two couplings: a marginal one and an irrelevant one .…
Thermodynamic topology of Einstein-Maxwell-Dilaton Theories
H. Babaei-Aghbolagh, Habib Esmaili, Song He +1
We present a systematic investigation of the thermodynamic topology for a broad class of asymptotically charged Anti-de Sitter (AdS) black holes in Einstein-Maxwell-Dilaton (EMD) t…
