Localization and topological signatures under periodic twisting
James Walkling, Antonio Štrkalj, F. Nur Ünal
We theoretically explore a dynamical generalization of the Aubry-André model in two dimensions formed by superimposing two square-lattice potentials. Motivated by the rich physics…

Aharonov-Bohm interferometer in inverted-band pn junctions
Yuhao Zhao, Oded Zilberberg, Antonio Štrkalj
Inverted-band junctions in two-dimensional materials offer a promising platform for electron optics in condensed matter, as they allow to manipulate and guide electron beams w…

Reentrant localisation transitions and anomalous spectral properties in off-diagonal quasiperiodic systems
Hugo Tabanelli, Claudio Castelnovo, Antonio Štrkalj
We investigate the localisation properties of quasiperiodic tight-binding chains with hopping terms modulated by the interpolating Aubry-André-Fibonacci (IAAF) function. This off-d…
