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…
Quantum cosmology of a conformal multiverse
Salvador J. Robles-Perez
In this paper it is studied the cosmology of a homogeneous and isotropic spacetime endorsed with a conformally coupled massless scalar field. We find six different solutions of the…
Invariant vacuum
Salvador Robles-Perez
We apply the Lewis-Riesenfeld invariant method for the harmonic oscillator with time dependent mass and frequency to the modes of a charged scalar field that propagates in a curved…
Observational consequences of an interacting multiverse
Salvador J. Robles-Perez
The observability of the multiverse is at the very root of its physical significance as a scientific proposal. In this conference we present, within the third quantization formalis…
