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…
Topological phases of the interacting Su-Schrieffer-Heeger model: An analytical study
E. Di Salvo, A. Moustaj, C. Xu +4
The interacting SSH model provides an ideal ground to study the interplay between topologically insulating phases and electron-electron interactions. We study the polarization dens…
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.…
Anomalous Polarization in One-dimensional Aperiodic Insulators
A. Moustaj, J. P. J. Krebbekx, C. Morais Smith
By implementing a charge pumping scheme for one-dimensional aperiodic chains, we confirm the existence of topological phases in these systems whenever their finite-size realization…
