Observation of Local Symmetry in a Photonic System
Nora Schmitt, Steffen Weimann, Christian V. Morfonios +4
The concept of local symmetry is a powerful tool in predicting complex transport phenomena in aperiodic media. A nonlocal continuity formalism reveals how local symmetries are enco…

Photonic Topological Insulator in Synthetic Dimensions
Eran Lustig, Steffen Weimann, Yonatan Plotnik +4
Topological phases enable protected transport along the edges of materials, offering immunity against scattering from disorder and imperfections. These phases were suggested and de…

Transport in Sawtooth photonic lattices
Steffen Weimann, Luis Morales-Inostroza, Bastián Real +3
We investigate, theoretically and experimentally, a photonic realization of a Sawtooth lattice. This special lattice exhibits two spectral bands, with one of them experiencing a co…
