Gravity in the brane-world for two-branes model with stabilized modulus
Takahiro Tanaka, Xavier Montes
We present a complete scheme to discuss linear perturbations in the two-branes model of the Randall and Sundrum scenario with the stabilization mechanism proposed by Goldberger and…
Renormalized stress tensor in one-bubble spacetimes
Xavier Montes
We compute the two-point function and the renormalized expectation value of the stress tensor of a quantum field interacting with a nucleating bubble. Two simple models are conside…
Microwave background anisotropies in quasiopen inflation
Juan Garcia-Bellido, Jaume Garriga, Xavier Montes
Quasiopenness seems to be generic to multi-field models of single-bubble open inflation. Instead of producing infinite open universes, these models actually produce an ensemble of…
Spectrum of Cosmological Perturbations in the One-Bubble Open Universe
Jaume Garriga, Xavier Montes, Misao Sasaki +1
The spectrum of cosmological perturbations in the context of the one-bubble open inflation model is discussed, taking into account fluctuations of the metric. We find that, quite g…
Quasi-open inflation
Juan Garcia-Bellido, Jaume Garriga, Xavier Montes
We show that a large class of two-field models of single-bubble open inflation do not lead to infinite open universes, as it was previously thought, but to an ensemble of very larg…
