Tuning topological phases and exceptional points in a non-Hermitian Rice Mele model beyond nearest neighbors
Carolina Martinez-Strasser, Dario Bercioux, Nico Leumer
Exceptional points are degeneracies characteristic of non-Hermitian operators, where eigenvalues and eigenvectors coalesce, rendering the Hamiltonian defective. We investigate the…

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…
