Wormholes in Simplicial Minisuperspace
Cristovao Correia da Silva, Ruth M. Williams
Using simplicial minisuperspace techniques we obtain a wormhole configuration, capable of modelling both a throat between two equal Euclidean and Lorentzian universes. Computing th…
Simplicial minisuperspace models in the presence of a massive scalar field with arbitrary scalar coupling
Cristovao Correia da Silva, Ruth M. Williams
We extend previous simplicial minisuperspace models to account for arbitrary scalar coupling ηRϕ^2.
Anisotropic simplicial minisuperspace model
Cristovao Correia da Silva, Ruth M. Williams
The computation of the simplicial minisuperspace wavefunction in the case of anisotropic universes with a scalar matter field predicts the existence of a large classical Lorentzian…
Simplicial minisuperspace models in the presence of a scalar field
C. Correia da Silva, R. M. Williams
We generalize simplicial minisuperspace models associated with restricting the topology of the universe to be that of a cone over a closed connected combinatorial manifold by c…
