Higher-order topological pumping and its observation in photonic lattices
Wladimir A. Benalcazar, Jiho Noh, Mohan Wang +3
The discovery of the quantization of particle transport in adiabatic pumping cycles of periodic structures by Thouless [Phys. Rev. B 27, 6083 (1983)] linked the Chern number, a top…
Continuously tuning the refractive indices by restructuring materials on the 20-1000 atoms scale: improving anti-reflection coating designs
Jacob Poole, Aidong Yan, Paul Ohodnicki +1
We demonstrate the capability of block-copolymer templating to tune the refractive indices of functional oxides over a broad range by structuring materials on the 20-1000 atoms sca…
Braiding photonic topological zero modes
Jiho Noh, Thomas Schuster, Thomas Iadecola +5
A remarkable property of quantum mechanics in two-dimensional (2D) space is its ability to support "anyons," particles that are neither fermions nor bosons. Theory predicts that th…
Experimental realization of a Weyl exceptional ring
Alexander Cerjan, Sheng Huang, Kevin P. Chen +2
Weyl points are isolated degeneracies in reciprocal space that are monopoles of the Berry curvature. This topological charge makes them inherently robust to Hermitian perturbations…
Photonic Realization of a Transition Between Topological Phases Residing in the Weak and Strong Floquet Driving Regimes
Jonathan Guglielmon, Sheng Huang, Kevin P. Chen +1
A photonic Floquet topological insulator has previously been experimentally realized in an array of evanescently-coupled helical waveguides. In the topological regime probed by tha…
Observation of Photonic Topological Valley-Hall Edge States
Jiho Noh, Sheng Huang, Kevin Chen +1
We experimentally demonstrate topological edge states arising from the valley-Hall effect in twodimensional honeycomb photonic lattices with broken inversion symmetry. We break inv…
