Are we survivors of the sudden past singularity?
Adam Balcerzak, Tomasz Denkiewicz, Mateusz Lisaj
In this paper, we investigate the viability of cosmological models featuring a type II singularity that occurs during the past evolution of the Universe. We construct a scenario in…
Spinor wave function of the Universe in non-minimally coupled varying constants cosmologies
Adam Balcerzak, Mateusz Lisaj
In this paper, we introduce a non-minimally coupled varying speed of light and varying gravitational constant cosmological toy model. Using the Eisenhart-Duval lifting method, we e…
Decaying universes and the emergence of Bell-type interuniversal entanglement in varying fundamental constants cosmological model
Adam Balcerzak, Mateusz Lisaj
In this paper, we consider a high-curvature limit of the varying fundamental constants toy model in which both the value of the speed of light and the value of the gravitational co…
Entanglement entropy at critical points of classical evolution in oscillatory and exotic singularity multiverse models
Adam Balcerzak, Samuel Barroso-Bellido, Mariusz P. Dabrowski +1
Using the 3rd quantization formalism we study the quantum entanglement of universes created in pairs within the framework of standard homogeneous and isotropic cosmology. In partic…
Doubleverse entanglement in third quantized non-minimally coupled varying constants cosmologies
Adam Balcerzak, Konrad Marosek
In this paper we consider a third quantized cosmological model with varying speed of light and varying gravitational constant both represented by non-minimally coupled scal…
Emergence of multiverse in third quantized varying constants cosmologies
Adam Balcerzak, Konrad Marosek
Although the standard cosmological model explains most of the observed phenomena it still struggles with the problem of initial singularity. An interesting scenario in which the pr…
