Helical transport in coupled resonator waveguides
JungYun Han, Clemens Gneiting, Daniel Leykam
We show that a synthetic pseudospin-momentum coupling can be used to design quasi-one-dimensional disorder-resistant coupled resonator optical waveguides (CROW). In this structure,…
Edge Modes, Degeneracies, and Topological Numbers in Non-Hermitian Systems
Daniel Leykam, Konstantin Y. Bliokh, Chunli Huang +2
We analyze chiral topological edge modes in a non-Hermitian variant of the 2D Dirac equation. Such modes appear at interfaces between media with different "masses" and/or signs of…
Observation of transverse coherent backscattering in disordered photonic structures
Sebastian Brake, Martin Boguslawski, Daniel Leykam +2
We report on the experimental observation of weak localization in an optically induced disordered (2+1)-dimensional photonic structure. Our flexible method of optical induction is…
Flat Bands Under Correlated Perturbations
Joshua D. Bodyfelt, Daniel Leykam, Carlo Danieli +2
Flat band networks are characterized by coexistence of dispersive and flat bands. Flat bands (FB) are generated by compact localized eigenstates (CLS) with local network symmetries…
