Effects of Gravitational Chern-Simons during Axion-SU(2) Inflation
Leila Mirzagholi, Eiichiro Komatsu, Kaloian D. Lozanov +1
In this paper, we examine the viability of inflation models with a spectator axion field coupled to both gravitational and SU(2) gauge fields via Chern-Simons couplings. Requiring…
Multi-disformal invariance of nonlinear primordial perturbations
Yuki Watanabe, Atsushi Naruko, Misao Sasaki
We study disformal transformations of the metric in the cosmological context. We first consider the disformal transformation generated by a scalar field and show that the curva…
Solar system and equivalence principle constraints on f(R) gravity by chameleon approach
Salvatore Capozziello, Shinji Tsujikawa
We study constraints on f(R) dark energy models from solar system experiments combined with experiments on the violation of equivalence principle. When the mass of an equivalent sc…
Conditions for the cosmological viability of f(R) dark energy models
Luca Amendola, Radouane Gannouji, David Polarski +1
We derive the conditions under which dark energy models whose Lagrangian densities f are written in terms of the Ricci scalar R are cosmologically viable. We show that the cosmolog…
Avoidance of future singularities in loop quantum cosmology
M. Sami, Parampreet Singh, Shinji Tsujikawa
We consider the fate of future singularities in the effective dynamics of loop quantum cosmology. Non-perturbative quantum geometric effects which lead to modification of the…
