Geometrical control of topology with orbital angular momentum modes

Yunjia Zhai, Anselmo M. Marques, Ricardo G. Dias +2

We study how the topological properties of a one-dimensional staggered lattice, loaded into states with orbital angular momentum $l = 1$ , can be controlled simply by tuning the relat…

Exceptional horns in $n$ -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 $n$ th roots of those of Hermitian parent two-dimensional (2D) lattices, namely…
