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…

Toward a simultaneous resolution of the $H_{0}$ and $S_{8}$ tensions: early dark energy and an interacting dark sector model

Mai Yashiki

The tension between the Hubble constant ( $H_{0}$ ) inferred from the cosmic microwave background (CMB) and that measured from late-time observations, such as the local distance ladder…

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…
