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…
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…
Fractal Nodal Band Structures
Marcus Stålhammar, Cristiane Morais Smith
Non-Hermitian systems exhibit interesting band structures, where novel topological phenomena arise from the existence of exceptional points at which eigenvalues and eigenvectors co…
Visualising the connection between edge states and the mobility edge in adiabatic and non-adiabatic topological charge transport
Mariya A. Lizunova, Florian Schreck, Cristiane Morais Smith +1
The ability to pump quantised amounts of charge is one of the hallmarks of topological materials. An archetypical example is Laughlin's gauge argument for transporting an integer n…
Strongly interacting bosons in a 1D optical lattice at incommensurate densities
Achilleas Lazarides, Olivier Tieleman, Cristiane Morais Smith
We investigate quantum phase transitions occurring in a system of strongly interacting ultracold bosons in a 1D optical lattice. After discussing the commensurate-incommensurate tr…
