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…

Non-Hermitian spacetime and generalized thermofield double formalism
Wu-zhong Guo, Tao Liu
In this paper, we explore the non-Hermitian transition matrix and its gravity dual. States in quantum field theories or gravity theories are typically prepared using Euclidean path…

Higgs-Portal Dark Matter in Brane-World Cosmology
Taoli Liu, Nobuchika Okada, Digesh Raut
The Higgs-portal scalar dark matter (DM) model is a simple extension of the Standard Model (SM) to incorporate a DM particle to the SM, where a -odd real scalar field is intro…
