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…

Spectral intertwining relations in exactly solvable quantum-mechanical systems

Tsuyoshi Houri, Makoto Sakamoto, Kentaro Tatsumi

In exactly solvable quantum-mechanical systems, ladder and intertwining operators play a central role because, if they are found, the energy spectra can be obtained algebraically.…

Supersymmetry in 6d Dirac Action

Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +2

We investigate a 6d Dirac fermion on a rectangle. It is found that the 4d spectrum is governed by supersymmetric quantum mechanics. Then we demonstrate that the supersymmetry…

6d Dirac fermion on a rectangle; scrutinizing boundary conditions, mode functions and spectrum

Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +2

We classify possible boundary conditions of a 6d Dirac fermion on a rectangle under the requirement that the 4d Lorentz structure is maintained, and derive the profiles and spe…

Active Dirac Neutrinos via Doublets in 5d

Yukihiro Fujimoto, K. Hasegawa, Tomoaki Nagasawa +3

We propose a new mechanism to generate minuscule active neutrino masses in a five-dimensional~(5d) spacetime of an interval without introducing singlet neutrinos. Under a…
