Realization of a one-dimensional topological insulator in ultrathin germanene nanoribbons
Dennis J. Klaassen, Lumen A. G. Eek, Alexander N. Rudenko +9
Realizing a one-dimensional (1D) topological insulator and identifying the lower dimensional limit of two-dimensional (2D) behavior are crucial steps toward developing high-density…
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…
Latent Haldane Models
Anouar Moustaj, Lumen Eek, Malte Rontgen +1
Latent symmetries, which materialize after performing isospectral reductions, have recently been shown to be instrumental in revealing novel topological phases in one-dimensional s…
Haldane model on the Sierpiński gasket
Zebedeus Osseweijer, Lumen Eek, Anouar Moustaj +2
We investigate the topological phases of the Haldane model on the Sierpiński gasket. As a consequence of the fractal geometry, multiple fractal gaps arise. Additionally, a flat ban…
Higher-order topology protected by latent crystalline symmetries
L. Eek, M. Röntgen, A. Moustaj +1
We demonstrate that rotation symmetry is not a necessary requirement for the existence of fractional corner charges in Cn-symmetric higher-order topological crystalline insulators.…
