Exceptional horns in -root graphene and Lieb photonic ring lattices
A. M. Marques, D. Viedma, V. Ahufinger +1
We present a systematic construction of non-Hermitian tight-binding lattices whose Bloch spectra are th roots of those of Hermitian parent two-dimensional (2D) lattices, namely…

High-root topological edge-state bands
R. G. Dias, L. Madail, A. M. Marques
This paper presents a complex band analysis of one-dimensional (1D) square and high-root topological insulators (HRTIs). We show that edge-state bands of HRTIs are sliced sections…
