Warm λ 4 ϕ 4
Videla, Nelson; Panotopoulos, Grigorios
In the present work we show that warm chaotic inflation characterized by a simple
Warm intermediate inflation in the Randall–Sundrum II model in the light of Planck 2015 and BICEP2 results: a general dissipative coefficient
Videla, Nelson; Herrera, Ramón; Olivares, Marco
A warm inflationary Universe in the Randall–Sundrum II model during intermediate inflation is studied. For this purpose, we consider the general form for the dissipative coefficient
X-ray lines and self-interacting dark matter
Mambrini, Yann; Toma, Takashi
We study the correlation between a monochromatic signal from annihilating dark matter and its self-interacting cross section. We apply our argument to a complex scalar dark sector, where the pseudo-scalar plays the role of a warm dark matter candidate while the scalar mediates its interaction with the Standard Model. We combine the recent observat…
Nearly scale-invariant power spectrum and quantum cosmological perturbations in the gravity's rainbow scenario
Wang, Sai; Chang, Zhe
We propose the gravity's rainbow scenario as a possible alternative of the inflation paradigm to account for the flatness and horizon problems. We focus on studying the cosmological scalar perturbations which are seeded by the quantum fluctuations in the very early universe. The scalar power spectrum is expected to be nearly scale-invariant. We es…
