A bstract We define a new complex-valued measure of information called the timelike
entanglement entropy (EE) which in the boundary theory can be viewed as a Wick rotation …

A bstract We develop a new setting in the framework of braneworld holography to describe a
pair of coupled and entangled uniformly accelerated universes. The model consists of two …

We refine previous investigations on de Sitter space and extremal surfaces anchored at the
future boundary I+. Since such surfaces do not return, they require extra data or boundary …

The concept of space evolution (or space-time duality) has emerged as a promising
approach for studying quantum dynamics. The basic idea involves exchanging the roles of …

A bstract A long-standing and intriguing question is: does the holographic principle apply to
cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein …

A bstract We study the entanglement entropy for time-like subsystem in two-dimensional
boundary conformal field theory (BCFT) both from the field theory and holographic point of …

A bstract In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after
local primary operator quenches in 2D CFTs with\(T\overline {T}/J\overline {T}\)-deformation …

A bstract In the context of dS 3/CFT 2, we propose a timelike entanglement entropy defined
by the renormalization group flow. This timelike entanglement entropy is calculated in CFT …

A bstract In order to study the pseudo entropy of timelike subregions holographically, the
previous smooth space-like extremal surface was recently generalized to mix space-like and …
