Fermionic quantum cosmology as a framework for resolving type IV singularities

European Physical Journal C: Particles and Fields
In this paper, we present an innovative approach to resolving type IV singularities in fermionic quantum cosmology. The Eisenhart–Duval lift procedure is employed to construct an extended minisuperspace metric, which allows for the formulation of the ...

Monte Carlo studies of quantum cosmology by the generalized Lefschetz thimble method

Journal of High Energy Physics
Quantum cosmology aims at elucidating the beginning of our Universe. Back in early 80’s, Vilenkin and Hartle-Hawking put forward the “tunneling from nothing” and “no boundary” proposals.
