Ordering-Independent Wheeler-DeWitt Equation for Flat Minisuperspace Models
Victor Franken, Eftychios Kaimakkamis, Hervé Partouche +1
We consider minisuperspace models with two-derivative kinetic terms, assuming a flat target space and a closed Universe. We show that, upon canonical quantization of the Hamiltonia…
Holography for de Sitter bubble geometries
Anastasios Irakleous, François Rondeau, Nicolaos Toumbas
We generalize the de Sitter static patch holographic proposal and the bilayer holographic entanglement entropy prescription to de Sitter geometries containing a bubble of smaller p…
Subleading soft radiation during scattering of dressed states in QED
Stavros Christodoulou, Nicolaos Toumbas
We study soft photon emission during scattering of Faddeev-Kulish charged states in QED, at leading order in perturbation theory. The charged asymptotic particles are accompanied b…
The exact Wheeler-DeWitt equation for the scale-factor minisuperspace model
Eftychios Kaimakkamis, Hervé Partouche, Karunava Sil +1
We consider the classical minisuperspace model describing a closed, homogeneous and isotropic Universe, with a positive cosmological constant. Upon canonical quantization, the infi…
Closed FRW holography: A time-dependent ER=EPR realization
Victor Franken, Hervé Partouche, François Rondeau +1
We extend a recent de Sitter holographic proposal and entanglement entropy prescription to generic closed FRW cosmologies in arbitrary dimensions, and propose that for large classe…
