Journal ArticleDOI
Topological States and adiabatic pumping in quasicrystals.
TL;DR: It is shown, both theoretically and experimentally, that one-dimensional quasicrystals are assigned two-dimensional Chern numbers and, respectively, exhibit topologically protected boundary states equivalent to the edge states of a two- dimensional quantum Hall system.
Journal ArticleDOI
Photonic topological boundary pumping as a probe of 4D quantum Hall physics
Oded Zilberberg,Sheng Huang,Jonathan Guglielmon,Mohan Wang,Kevin P. Chen,Yaacov E. Kraus,Mikael C. Rechtsman +6 more
TL;DR: This work uses tunable 2D arrays of photonic waveguides to realize a dynamically generated four-dimensional (4D) quantum Hall system experimentally, and provides a platform for the study of higher-dimensional topological physics.
Journal ArticleDOI
Observation of Topological Phase Transitions in Photonic Quasicrystals
TL;DR: In this paper, a smooth boundary between topologically distinct one-dimensional quasicrystals was constructed by constructing a boundary between the Harper and Fibonacci lattice, and the same method was used to experimentally confirm the topological equivalence between the two lattice types.
Journal ArticleDOI
Topological Equivalence between the Fibonacci Quasicrystal and the Harper Model
Yaacov E. Kraus,Oded Zilberberg +1 more
TL;DR: It is shown that this deformation does not close any bulk gaps, and thus it is proved that these models are in fact topologically equivalent, and regardless of whether the quasiperiodicity appears as an on-site or hopping modulation.
Journal ArticleDOI
Four-dimensional quantum Hall effect in a two-dimensional quasicrystal.
TL;DR: It is shown that a previously inaccessible phase of matter-the 4D integer quantum Hall effect-can be incorporated in a 2D quasicrystal, and may pave the way to the experimental study of 4D physics.
