Eigenvalue topology of non-Hermitian band structures in two and three dimensions
Charles C. Wojcik, Kai Wang, Avik Dutt +2
In the band theory for non-Hermitian systems, the energy eigenvalues, which are complex, can exhibit non-trivial topology which is not present in Hermitian systems. In one dimensio…

Non-trivial point-gap topology and non-Hermitian skin effect in photonic crystals
Janet Zhong, Kai Wang, Yubin Park +4
We show that two-dimensional non-Hermitian photonic crystals made of lossy material can exhibit non-trivial point gap topology in terms of topological winding in its complex freque…
