Partial chiral symmetry-breaking as a route to spectrally isolated topological defect states in two-dimensional artificial materials
Charles Poli, Henning Schomerus, Matthieu Bellec +2
Bipartite quantum systems from the chiral universality classes admit topologically protected zero modes at point defects. However, in two-dimensional systems these states can be di…

Universal sign-control of coupling in tight-binding lattices
Robert Keil, Charles Poli, Matthias Heinrich +4
We present a method of locally inverting the sign of the coupling term in tight-binding systems, by means of inserting a judiciously designed ancillary site and eigenmode matching…
