Weyl invariant Dirac-Born-Infeld-Einstein theory
Nahomi Kan, Takuya Maki, Kiyoshi Shiraishi
We consider a Weyl invariant extension of Dirac-Born-Infeld type gravity. An appropriate choice of the metric hides the scalar degree of freedom which is required by the local scal…
Interparticle Potential up to Next-to-leading Order for Gravitational, Electrical, and Dilatonic Forces
Nahomi Kan, Kiyoshi Shiraishi
Long-range forces up to next-to-leading order are computed in the framework of the Einstein-Maxwell-dilaton system by means of a semiclassical approach to gravity. As has been rece…
Classical and Quantum Cosmology of Multigravity
Teruki Hanada, Koichiro Kobayashi, Kazuhiko Shinoda +1
Recently, a multigraviton theory on a simple closed circuit graph corresponding to the discretization of compactification of the Kaluza-Klein (KK) theory has been considered.…
Boson Stars under Deconstruction
Nahomi Kan, Kiyoshi Shiraishi
We study solutions for boson stars in multiscalar theory. We start with simple models with N scalar theories. Our purpose is to study the models in which the mass matrix of scalars…
