Holographic CCFT Pseudo-Entropy
Reza Fareghbal, Abolfazl Hassani Majoulan
According to the flat/CCFT correspondence, Carrollian conformal field theories (CCFT) in d dimensions are dual to asymptotically flat spacetimes in d+1 dimensions. In this paper, s…
Flat-Space Limit of Holographic Pseudo Entropy in (A)dS Spacetimes
Reza Fareghbal
The real part of pseudo entropy in conformal field theories is holographically calculated by the area of some extremal spacelike surfaces in the dual dS and AdS spacetimes. We show…
Dominant Spacetime in Three Dimensional de Sitter Gravity
Reza Fareghbal, Vahid Reza Shajiee
In three dimensions, Kerr-de Sitter spacetime as a solution of Einstein gravity with positive cosmological constant has a single cosmological horizon. The flat-space limit (zero co…
Islands in Kerr-de Sitter spacetime and their flat limit
Sanam Azarnia, Reza Fareghbal
We use quantum extremal island method to study the information paradox on certain cosmological setups known as three dimensional Kerr-de Sitter spacetimes. To do so, we couple an a…
Islands in Flat-Space Cosmology
Sanam Azarnia, Reza Fareghbal, Ali Naseh +1
Flat-space cosmologies (FSC) are solutions to three dimensional theories of gravity without cosmological constant that have cosmological horizons. A detector located near the time-…
Flat-space Limit of Extremal Curves
Reza Fareghbal, Mehdi Hakami Shalamzari, Pedram Karimi
According to the Ryu-Takayanagi prescription, the entanglement entropy of subsystems in the boundary conformal field theory (CFT) is proportional to the area of extremal surfaces i…
