DBI scalar field cosmology in $n$ -DBI gravity

Nahomi Kan, Kiyoshi Shiraishi, Maki Takeuchi +1

We study inflationary characterictics of the universe in $n$ -DBI gravity, driven by DBI-deformed scalar fields. In this paper, we consider the evolution of the classical universe f…

Quantum BPS Cosmology

Nahomi Kan, Kiyoshi Shiraishi, Maki Takeuchi +1

There has been much discussion about the initial conditions of the early Universe in the context of quantum theory. In this paper, we construct the wave function and probability di…

Classical and quantum cosmology of $K$ -essentially modified $R^{2}$ and pure $R^{p}$ gravity

Nahomi Kan, Kiyoshi Shiraishi, Mai Yashiki

We present a gravitational action with a modified higher order term of a combination of scalar curvature and Lagrangian density of a scalar field. This type of models has been cons…
