Emergent -type topology in a quasi-one-dimensional extended QWZ model
Zebedeus F. Osseweijer, Lumen Eek, Cristiane Morais Smith
We investigate the emergence of zero-dimensional topological end states in nanoribbons described by the Qi-Wu-Zhang (QWZ) model and its extensions with longer-range couplings. Whil…
Universality of dimensional crossovers in topological insulators
Lumen Eek, Zeb Osseweijer, Cristiane Morais Smith
We investigate dimensional crossovers in minimal tight-binding models of three-dimensional (3D) topological insulators subject to geometric confinement. While thin films are common…
Topology of honeycomb nanoribbons revisited
Zebedeus F. Osseweijer, Lumen Eek, Harold J. W. Zandvliet +2
We present an in-depth study of end states in honeycomb nanoribbons, focusing on the interplay between nanoribbon termination, chiral symmetry, and complex next-nearest-neighbor ho…
Fractality-induced Topology
L. Eek, Z. F. Osseweijer, C. Morais Smith
Fractal geometries, characterized by self-similar patterns and non-integer dimensions, provide an intriguing platform for exploring topological phases of matter. In this work, we i…
