5. 6d Dirac fermion on a rectangle; scrutinizing boundary conditions, mode functions and spectrum / Fujimoto, Yukihiro ; Hasegawa, Kouhei ; Nishiwaki, Kenji ; Sakamoto, Makoto ; et al
We classify possible boundary conditions of a 6d Dirac fermion Ψ on a rectangle under the requirement that the 4d Lorentz structure is maintained, and derive the profiles and spectrum of the zero modes and nonzero KK modes under the two specific boundary conditions, (i) 4d-chirality positive components being zero at the boundaries and (ii) internal chirality positive components being zero at the boundaries.
