Flux-induced midgap states between strain-engineered flat bands
Dung Xuan Nguyen, Jake Arkinstall, Henning Schomerus
Half-integer quantized flux vortices appear in honeycomb lattices when the signs of an odd number of couplings around a plaquette are inverted. We show that states trapped at these…
Topological tight-binding models from non-trivial square roots
J. Arkinstall, M. H. Teimourpour, L. Feng +2
We describe a versatile mechanism that provides tight-binding models with an enriched, topologically nontrivial bandstructure. The mechanism is algebraic in nature, and leads to ti…
Degeneracy doubling and sublattice polarization in strain-induced pseudo-Landau levels
Charles Poli, Jake Arkinstall, Henning Schomerus
The degeneracy and spatial support of pseudo-Landau levels (pLLs) in strained honeycomb lattices systematically depends on the geometry -- for instance, in hexagonal and rectangula…
