Strongly scale-dependent CMB dipolar asymmetry from super-curvature fluctuations
Christian Byrnes, Guillem Domènech, Misao Sasaki +1
We reconsider the observed CMB dipolar asymmetry in the context of open inflation, where a supercurvature mode might survive the bubble nucleation. If such a supercurvature mode mo…
Consistency relation and inflaton field redefinition in the delta N formalism
Guillem Domenech, Jinn-Ouk Gong, Misao Sasaki
We compute for general single-field inflation the intrinsic non-Gaussianity due to the self-interactions of the inflaton field in the squeezed limit. We recover the consistency rel…
Stationary bubbles: information loss paradox?
Guillem Domènech, Misao Sasaki
The main purpose of this work is to build classically stationary bubbles, within the thin-shell formalism, which are unstable under quantum effects; they either collapse into a bla…
Conformal frames in cosmology
Guillem Domènech, Misao Sasaki
From higher dimensional theories, e.g. string theory, one expects the presence of non-minimally coupled scalar fields. We review the notion of conformal frames in cosmology and emp…
