We study holographic entanglement entropy in dS/CFT and introduce timelike entanglement
entropy in CFTs. Both of them take complex values in general and are related with each …

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 …

We present a general framework in which both Krylov state and operator complexities can
be put on the same footing. In our formalism, the Krylov complexity is defined in terms of the …

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 …

A bstract In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with
scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds …

We develop further the investigations by Narayan [de Sitter space, extremal surfaces, and
time entanglement, Phys. Rev. D 107, 126004 (2023) PRVDAQ 2470-0010 …
