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…
Energy density as a probe of band representations in photonic crystals
M. Blanco de Paz, M. A. J. Herrera, P. Arroyo Huidobro +6
Topological Quantum Chemistry (TQC) has recently emerged as a instrumental tool to characterize the topological nature of both fermionic and bosonic band structures. TQC is based o…
Corner modes of the breathing kagome lattice: origin and robustness
M. A. J. Herrera, S. N. Kempkes, M. Blanco de Paz +3
We study the non-trivial phase of the two-dimensional breathing kagome lattice, displaying both edge and corner modes. The corner localized modes of a two-dimensional flake were in…
