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 , can be controlled simply by tuning the relat…
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…
Topological bound states in a lattice of rings with nearest-neighbour interactions
Yunjia Zhai, Ayaka Usui, Anselmo M. Marques +2
We study interaction-induced bound states in a system of ultracold bosons loaded into the states with orbital angular momentum in a one-dimensional staggered lattice of rings. We c…
Effects of Peierls phases in open linear chains
Anselmo M. Marques
The introduction of Peierls phases in open tight-binding chains without closed paths in either real or synthetic dimensions is understood to be physically inconsequential, as one a…
Flux-mediated effective Su-Schrieffer-Heeger model in an impurity decorated diamond chain
David Viedma, Anselmo M. Marques, Ricardo G. Dias +1
In flat-band systems with non-orthogonal compact localized states (CLSs), onsite perturbations couple neighboring CLSs and generate exponentially-decaying impurity states, whose de…
Impurity flat band states in the diamond chain
Anselmo M. Marques, David Viedma, Verònica Ahufinger +1
Flat band (FB) systems, featuring dispersionless energy bands, have garnered significant interest due to their compact localized states (CLSs). However, a detailed account on how l…
Topological -root Su-Schrieffer-Heeger model in a non-Hermitian photonic ring system
David Viedma, Anselmo M. Marques, Ricardo G. Dias +1
Square-root topology is one of the newest additions to the ever expanding field of topological insulators (TIs). It characterizes systems that relate to their parent TI through the…
