Higher-spin charges and the algebra in (A)dS
Lorenzo Di Giacomo, Maitá Micol, Daniele Pranzetti +1
We consider -dimensional asymptotically locally (anti-)de Sitter ((A)dS) spacetimes with boundary conditions allowing for gravitational flux. We construct an infinite to…
On bulk reconstruction in Lorentzian AdS and its flat space limit
Núria Navarro, Ana-Maria Raclariu
We revisit the reconstruction of a free quantum field in 4-dimensional Lorentzian Anti-de-Sitter (AdS) spacetime in terms of primary operators in the boundary 3d CFT (CFT).…
Null quantization, shadows and boost eigenfunctions in Lorentzian AdS
Núria Navarro, Ana-Maria Raclariu
We revisit the quantization of a free scalar in 4-dimensional (4d) Lorentzian Anti-de-Sitter spacetime (AdS). We derive solutions to the wave equation that diagonalize time tra…
Infinite towers of 2d symmetry algebras from Carrollian limit of 3d CFT
Leonardo Pipolo de Gioia, Ana-Maria Raclariu
We consider the Carrollian limit of OPE blocks of scalar primaries, spin-1 currents and the stress tensor in 3-dimensional conformal field theory (CFT). We demonstrate that the…
An Infrared On-Shell Action and its Implications for Soft Charge Fluctuations in Asymptotically Flat Spacetimes
Temple He, Ana-Maria Raclariu, Kathryn M. Zurek
We study the infrared on-shell action of Einstein gravity in asymptotically flat spacetimes, obtaining an effective, gauge-invariant boundary action for memory and shockwave spacet…
Entanglement, Soft Modes, and Celestial Holography
Hong Zhe Chen, Robert C. Myers, Ana-Maria Raclariu
We evaluate the vacuum entanglement entropy across a cut of future null infinity for free Maxwell theory in four-dimensional Minkowski spacetime. The Weyl invariance of 4D Maxwell…
