Entanglement of General Subregions in Time-Dependent States
Wu-zhong Guo, Song He, Tao Liu
We develop a unified framework for computing Rényi and entanglement entropies of arbitrary spacetime intervals in time-dependent states of -dimensional conformal field theor…
Entanglement first law for timelike entanglement entropy and linearized Einstein's equation
Guo-Ying Li, Mei-Hui Xiao, Song He +1
We extend the entanglement first law of conformal field theory (CFT) to timelike subregions. Focusing on intervals along the time direction of the boundary CFT, we show that the as…
Prospect on constraining environment-dependent dilaton model from gravitational redshift measurements
Li Hu, Rong-Gen Cai, Song He +4
Scalar-tensor gravity represents a natural extension of general relativity. This paper investigates a conformal scalar-tensor gravity, the environmentally dependent dilaton model,…
Hydrodynamical transports in generic AdS Gauss-Bonnet-scalar Gravity
Chenwei Tong, Rohit Mishra, Yanqi Wang +1
The experimentally observed temperature-dependent shear and bulk viscosities of the quark-gluon plasma (QGP), along with its apparent violation of the Kovtun-Son-Starinets (KSS) bo…
Geometric realization of stress-tensor deformed field theory
Yun-Ze Li, Yunfei Xie, Song He
We present a semiclassical framework in which stress-tensor deformations of a quantum field theory (QFT) reorganize into a gravitational action evaluated at a metric saddle. The de…
Holographic Correlators of Boundary/Crosscap CFTs in Two Dimensions
Yun-Ze Li, Yunfei Xie, Song He
This work explores holographic correlators within the frameworks of two-dimensional Boundary Conformal Field Theory (BCFT) and Crosscap Conformal Field Theory (XCFT). Utilizing the…
