Inverse scattering for waveguides in topological insulators

Guillaume Bal, Xixian Wang, Zhongjian Wang

This paper concerns the inverse scattering problem of a topologically non-trivial waveguide separating two-dimensional topological insulators. We consider the specific model of a D…

$Z_{2}$ classification of FTR symmetric differential operators and obstruction to Anderson localization

Guillaume Bal, Zhongjian Wang

This paper concerns the $Z_{2}$ classification of Fermionic Time-Reversal (FTR) symmetric partial differential Hamiltonians on the Euclidean plane. We consider the setting o…
