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…
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…
On the stability of open-string orbifold models with broken supersymmetry
Steven Abel, Thibaut Coudarchet, Hervé Partouche
We consider an open-string realisation of spontaneous breaking of supersymmetry in four-dimensional Minkowski spacetime. It is based on type IIB or…
