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…
A formalism for the ambiguities of the Wheeler-DeWitt equation
Eftychios Kaimakkamis, Karunava Sil
We study ambiguities in the precise formulation of the Wheeler-DeWitt equation for the wavefunction of the Universe that arise due to different operator orderings in the quantum Ha…
