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…
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…
Light fermion masses in partially deconstructed models
Nahomi Kan, Kiyoshi Shiraishi, Maki Takeuchi
Considering a theory space consisting of a large number of five-dimensional Dirac fermion field theories including background abelian gauge fields, we can construct a theory simila…
Electric and dilatonic fields of a charged massive particle at rest in the field of a charged dilaton black hole
Nahomi Kan, Kiyoshi Shiraishi
We study linear-perturbation equations for the two-body system of a charged dilaton black hole, of which dilaton coupling constant is , and a static particle with mass , elec…
Dynamical mass generation of spin-2 fields in de Sitter space for an symmetric model at large
Nahomi Kan, Kiyoshi Shiraishi
We consider the strong-coupling phase in a model of spin-2 field theory in de Sitter spacetime and the effective mass of spin-2 fields therein. In the strong-coupling phase,…
