Linking topological features of the Hofstadter model to optical diffraction figures
Francesco Di Colandrea, Alessio D'Errico, Maria Maffei +6
In two, three and even four spatial dimensions, the transverse responses experienced by a charged particle on a lattice in a uniform magnetic field are fully controlled by topologi…
Bloch-Landau-Zener dynamics induced by a synthetic field in a photonic quantum walk
Alessio D'Errico, Raouf Barboza, Rebeca Tudor +4
Quantum walks are processes that model dynamics in coherent systems. Their experimental implementations proved key to unveil novel phenomena in Floquet topological insulators. Here…
Topological properties of the long-range Kitaev chain with Aubry-André-Harper modulation
Joana Fraxanet, Utso Bhattacharya, Tobias Grass +3
We present a detailed study of the topological properties of the Kitaev chain with long-range pairing terms and in the presence of an Aubry-André-Harper on-site potential. Specific…
Bulk detection of time-dependent topological transitions in quenched chiral models
Alessio D'Errico, Francesco Di Colandrea, Raouf Barboza +5
The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read-out by measuring the m…
Circular dichroism in high-order harmonic generation: Heralding topological phases and transitions in Chern insulators
Alexis Chacón, Dasol Kim, Wei Zhu +10
Topological materials are of interest to both fundamental science and advanced technologies, because topological states are robust with respect to perturbations and dissipation. Ex…
Detection of Zak phases and topological invariants in a chiral quantum walk of twisted photons
F. Cardano, A. D'Errico, A. Dauphin +9
Topological insulators are fascinating states of matter exhibiting protected edge states and robust quantized features in their bulk. Here, we propose and validate experimentally a…
