Hosotani mechanism in higher dimensional Lee-Wick theory
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
Hosotani mechanism in higher-dimensional Lee-Wick theory is investigated. The symmetry breaking mechanism proposed by Hosotani is studied at one-loop level through a toy model in t…
Nambu-Jona-Lasinio Model and Deconstructed Dimension
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
The Nambu-Jona-Lasinio model with the mass matrix which appears in a deconstruction model is investigated. We consider two models. In Model A, a mass matrix belonging to a type use…
Critical Cosmology in Higher Order Gravity
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
We construct the higher order terms of curvatures in Lagrangians of the scale factor for the Friedmann-Lemaitre-Robertson-Walker universe, which are linear in the second derivative…
Equations of motion in Double Field Theory: from classical particles to quantum cosmology
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
The equation of motion for a point particle in the background field of double field theory is considered. We find that the motion is described by a geodesic flow in the doubled geo…
Flux vacua in Dirac-Born-Infeld type Einstein-Maxwell theory
Takuya Maki, Nahomi Kan, Koichiro Kobayashi +1
We study compactification of extra dimensions in a theory of Dirac-Born-Infeld (DBI) type gravity. We investigate the solution for Minkowski spacetime with an extra space.…
Einstein Universe under Deconstruction: the case with degenerate fermions
Nahomi Kan, Koichro Kobayashi, Kiyoshi Shiraishi
We study self-consistent static solutions for an Einstein universe in a graph-based induced gravity. In the generalization of the deconstruction model based on the graph, the eigen…
