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…
Quantum creation of a universe-antiuniverse pair
S. J. Robles-Perez
If one analyses the quantum creation of the universe, it turns out that the most natural way in which the universes can be created is in pairs of universes whose time flow is rever…
Time reversal symmetry in cosmology and the creation of a universe-antiuniverse pair
Salvador J. Robles-Perez
The classical evolution of the universe can be seen as a parametrised worldline of the minisuperspace, with the time variable the parameter that parametrises the worldline. The…
Pre-inflation from the multiverse: Can it solve the quadrupole problem in the cosmic microwave background?
João Morais, Mariam Bouhmadi-López, Manuel Kraemer +1
We analyze a quantized toy model of a universe undergoing eternal inflation using a quantum-field-theoretical formulation of the Wheeler-DeWitt equation. This so-called third quant…
What if? - Exploring the Multiverse through Euclidean wormholes
Mariam Bouhmadi-López, Manuel Kraemer, João Morais +1
We present Euclidean wormhole solutions describing possible bridges within the multiverse. The study is carried out in the framework of the third quantization. The matter content i…
Restoration of matter-antimatter symmetry in the multiverse
Salvador J. Robles-Perez
In the multiverse, the universes can be created in entangled pairs with spacetimes that are both expanding in terms of the time variables experienced by internal observers in their…
