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…
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…
