Band structures of generalized eigenvalue equation and conic section
Takuma Isobe, Tsuneya Yoshida, Yasuhiro Hatsugai
Band structures of several metamaterials are described by generalized eigenvalue equations where complex bands emerge even if the involved matrices are Hermitian. In this paper, we…
Exceptional points and non-Hermitian skin effects under nonlinearity of eigenvalues
Tsuneya Yoshida, Takuma Isobe, Yasuhiro Hatsugai
Band structures of metamaterials described by a nonlinear eigenvalue problem are beyond the existing topological band theory. In this paper, we analyze non-Hermitian topology under…
Non-Hermitian skin effect protected by glide symmetry
Sho Ishikawa, Tsuneya Yoshida
Although nonsymmorphic symmetry protects topology for Hermitian systems, non-Hermitian topological phenomena induced by such a unique topological structure remain el…
Hinge non-Hermitian skin effect in the single-particle properties of a strongly correlated f-electron system
Robert Peters, Tsuneya Yoshida
Non-Hermitian systems exhibit novel phenomena without Hermitian counterparts, such as exceptional points and the non-Hermitian skin effect. These non-Hermitian topological phenomen…
