DBI scalar field cosmology in -DBI gravity
Nahomi Kan, Kiyoshi Shiraishi, Maki Takeuchi +1
We study inflationary characterictics of the universe in -DBI gravity, driven by DBI-deformed scalar fields. In this paper, we consider the evolution of the classical universe f…

Isothermal spheres from grand partition functions in nonextensive statistical mechanics
Nahomi Kan, Takuya Maki, Kiyoshi Shiraishi
We analytically study isothermal spheres in the light of nonextensive statistical mechanics. The equations for the isothermal spheres are derived from the grand partition function…
