Hosotani mechanism in the "color"-singlet plasma
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
By projecting the partition function on the "color"-singlet state, we investigate the Hosotani mechanism in the fermion-gauge boson plasma. The present toy-model analysis of the on…
Magnetic monopoles in multi-vector boson theories
Koichiro Kobayashi, Nahomi Kan, Kiyoshi Shiraishi
A classical solution for a magnetic monopole is found in a specific multi-vector boson theory. We consider the model whose gauge group is broken by sigma-model fiel…
Critical Higher Order Gravities in Higher Dimensions
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
We show that the higher order gravity model proposed by Meissner and Olechowski has a graviton mode, a massive spin-two excitation and no scalar mode in a maximally symmetric space…
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…
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…
Equations of Motion in Double Field Theory: From Particles to Scale Factors
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
In double field theory, the equation of motion for a point particle in the background field is considered. We find that the motion is described by a geodesic flow in the doubled ge…
Fermion spectrum and localization on kinks in a deconstructed dimension
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
We study the deconstructed scalar theory having nonlinear interactions and being renormalizable. It is shown that the kink-like configurations exist in such models. The possible fo…
Cancellation of long-range forces in Einstein-Maxwell-dilaton system
Nahomi Kan, Koichiro Kobayashi, Teruki Hanada +1
We examine cancellation of long-range forces in Einstein-Maxwell-Dilatonic system. Several conditions of the equilibrium of two charged masses in general relativity is found by man…
Vortices and Superfields on a Graph
Nahomi Kan, Koichiro Kobayashi, Kiyoshi Shiraishi
We extend the dimensional deconstruction by utilizing the knowledge of graph theory. In the dimensional deconstruction, one uses the moose diagram to exhibit the structure of the `…
