Hamiltonian approach to 2nd order gauge invariant cosmological perturbations
Guillem Domènech, Misao Sasaki
In view of growing interest in tensor modes and their possible detection, we clarify the definition of tensor modes up to 2nd order in perturbation theory within the Hamiltonian fo…
Thermal activation of thin-shells in anti-de Sitter black hole spacetime
Pisin Chen, Guillem Domènech, Misao Sasaki +1
We investigate thermal activation of thin-shells around anti-de Sitter black holes. Under the thin-shell approximation, we extensively study the parameter region that allows a bubb…
CMB Scale Dependent Non-Gaussianity from Massive Gravity during Inflation
Guillem Domènech, Takashi Hiramatsu, Chunshan Lin +3
We consider a cosmological model in which the tensor mode becomes massive during inflation, and study the Cosmic Microwave Background (CMB) temperature and polarization bispectra a…
