Instantons and Berry's connections on quantum graph
Tomonori Inoue, Makoto Sakamoto, Inori Ueba
In this paper, we study non-Abelian Berry's connections in the parameter space of boundary conditions for Dirac zero modes on quantum graphs. We apply the ADHM construction, which…
Extended supersymmetry with central charges in Dirac action with curved extra dimensions
Inori Ueba
We discuss a new realization of -extended quantum-mechanical supersymmetry (QM SUSY) with central charges hidden in the four-dimensional (4D) mass spectrum of higher d…
Dynamical generation of quark/lepton mass hierarchy in an extra dimension
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +4
We show that the observed quark/lepton mass hierarchy can be realized dynamically on an interval extra dimension with point interactions. In our model, the positions of the point i…
5d Dirac fermion on quantum graph
Yukihiro Fujimoto, Tomonori Inoue, Makoto Sakamoto +2
In this paper, we investigate a five-dimensional Dirac fermion on a quantum graph that consists of a single vertex and loops. We find that the model possesses a rich structure…
Extended supersymmetry with central charges in higher dimensional Dirac action
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +3
A new realization of extended quantum-mechanical supersymmetry (QM SUSY) with central extension is investigated. We first show that two different sets of () supercharges…
Extended supersymmetry in Dirac action with extra dimensions
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +3
We investigate a new realization of extended quantum-mechanical supersymmetry. We first show that an quantum-mechanical supersymmetry is hidden in the four-dimensio…
