Wannier center spectroscopy to identify boundary-obstructed topological insulators
R. A. M. Ligthart, M. A. J. Herrera, A. Visser +3
The hallmark of topological crystalline insulators is the emergence of a robust electronic state in a bandgap localized at the boundary of the material. However, end, edge, and sur…

Topological properties of a non-Hermitian quasi-1D chain with a flat band
C. Martínez-Strasser, M. A. J. Herrera, A. García-Etxarri +3
The spectral properties of a non-Hermitian quasi-1D lattice in two of the possible dimerization configurations are investigated. Specifically, it focuses on a non-Hermitian diamond…
