Genesis of the Floquet Hofstadter butterfly
S. H. Kooi, A. Quelle, W. Beugeling +1
We investigate theoretically the spectrum of a graphene-like sample (honeycomb lattice) subjected to a perpendicular magnetic field and irradiated by circularly polarized light. Th…
Universalities of thermodynamic signatures in topological phases
S. N. Kempkes, A. Quelle, C. Morais Smith
Topological insulators (superconductors) are materials that host symmetry-protected metallic edge states in an insulating (superconducting) bulk. Although they are well understood,…
Topological Floquet states on a Möbius band irradiated by circularly polarised light
A. Quelle, W. Beugeling, C. Morais Smith
Topological states of matter in equilibrium, as well as out of equilibrium, have been thoroughly investigated during the last years in condensed-matter and cold-atom systems. Howev…
Dynamical competition between Quantum Hall and Quantum Spin Hall effects
Anton Quelle, Cristiane Morais Smith
In this paper we investigate the occurrence of quantum phase transitions in topological systems out of equi- librium. More specifically, we consider graphene with a sizable spin-or…
Nontrivial topological states on a Möbius band
W. Beugeling, A. Quelle, C. Morais Smith
In the field of topological insulators, the topological properties of quantum states in samples with simple geometries, such as a cylinder or a ribbon, have been classified and und…
