Competition and interplay between topology and quasi-periodic disorder in Thouless pumping of ultracold atoms
Shuta Nakajima, Nobuyuki Takei, Keita Sakuma +3
Robustness against perturbations lies at the heart of topological phenomena. If, however, a perturbation such as disorder becomes dominant, it may cause a topological phase transit…
Topologically quantized current in quasiperiodic Thouless pumps
Pasquale Marra, Muneto Nitta
Thouless pumps are topologically nontrivial states of matter with quantized charge transport, which can be realized in atomic gases loaded into an optical lattice. This topological…
Fractional quantization of charge and spin in topological quantum pumps
Pasquale Marra, Roberta Citro
Topological quantum pumps are topologically equivalent to the quantum Hall state: In these systems, the charge pumped during each pumping cycle is quantized and coincides with the…
Fractional quantization of the topological charge pumping in a one-dimensional superlattice
Pasquale Marra, Roberta Citro, Carmine Ortix
A one-dimensional quantum charge pump transfers a quantized charge in each pumping cycle. This quantization is topologically robust being analogous to the quantum Hall effect. The…
