Cosmology from random entanglement
Stefano Antonini, Martin Sasieta, Brian Swingle
We construct entangled microstates of a pair of holographic CFTs whose dual semiclassical description includes big bang-big crunch AdS cosmologies in spaces without boundaries. The…
Holographic measurement in CFT thermofield doubles
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
We extend the results of arXiv:2209.12903 by studying local projective measurements performed on subregions of two copies of a CFT in the thermofield double state and investi…
QFT in Curved Spacetime from Quantum Gravity: proper WKB decomposition of the gravitational component
Giulia Maniccia, Giovanni Montani, Stefano Antonini
Starting from a re-analysis of previous work, we construct the proper low energy quantum field theory (QFT) limit of a full quantum gravity theory in the Born-Oppenheimer approach.…
Accelerating cosmology from gravitational effective field theory
Stefano Antonini, Petar Simidzija, Brian Swingle +2
A large class of cosmologies have big-bang / big crunch spacetimes with time-symmetric backgrounds and asymptotically AdS Euclidean continuations suggesting a possible holog…
