Spontaneous symmetry breaking in cosmos: The hybrid symmetron as a dark energy switching device
K. Bamba, R. Gannouji, M. Kamijo +2
We consider symmetron model in a generalized background with a hope to make it compatible with dark energy. We observe a "no go" theorem at least in case of a conformal coupling. B…
Cosmological dynamics of non-minimally coupled scalar field system and its late time cosmic relevance
M. Sami, M. Shahalam, M. Skugoreva +1
We investigate the cosmological dynamics of non-minimally coupled scalar field system described by coupling with () and the field potential, $V(ϕ)=V_…
Light mass galileons: Cosmological dynamics, mass screening and observational constraints
Amna Ali, Radouane Gannouji, Md. Wali Hossain +1
In this paper, we examine the cosmological viability of a light mass galileon field consistent with local gravity constraints. The minimal, L_3=\Boxϕ(\partial_μϕ)^2, massless galil…
Generic f(R) theories and classicality of their scalarons
R. Gannouji, M. Sami, I. Thongkool
We study quantum stability bound on the mass of scalaron in generic theories of gravity. We show that in these scenarios, the scalaron mass increases faster with local densi…
