Geometrical optics in phase space
I. Y. Dodin, N. A. Lopez, Tingjing Xing +2
Geometrical optics (GO) is widely used for reduced modeling of waves in plasmas but fails near reflection points, where it predicts a spurious singularity of the wave amplitude. We…

Counting topological interface modes using simplicial characteristic classes
N. Bohlsen, I. Y. Dodin, H. Qin
A computational approach for predicting the number of topological interface modes (TIMs) in hermitian systems using the spectral flow - monopole (SFM) correspondence is presented.…
