Wide-angle emission in cylindrical moiré lattices enabled by rolling origami
Min Tang, Fanzhou Lv, Haiyun Dong +8
Twisted photonic lattices that form moiré superlattices have attracted significant attention owing to their unique properties, such as strong field confinement and high-quality fac…
Probing Local Topology in a Disordered Higher-Order Topological Insulator
Johannes Düreth, Simon Widmann, Philipp Gagel +13
Higher-order topology is prized for its ability to realize lower-dimensional boundary states which are stable beyond fine-tuning. However, disorder presents a failure mechanism tha…
Artificial Gauge Fields and Dimensions in a Polariton Hofstadter Ladder
Simon Widmann, Jonas Bellmann, Johannes Düreth +11
Artificial gauge fields allow uncharged particles to mimic the behavior of charged particles subjected to magnetic fields, providing a powerful platform for exploring topological p…
Plasmonic Su-Schrieffer-Heeger chains with strong coupling amplitudes
Benedikt Schurr, Matthias Hensen, Luisa Brenneis +6
Plasmonic many-particle systems with precisely tuned resonances and coupling strengths can exhibit emergent collective properties governed by universal principles. In one-dimension…
Giant non-reciprocity and gyration through modulation-induced Hatano-Nelson coupling in integrated photonics
Ogulcan E. Orsel, Jiho Noh, Penghao Zhu +4
Asymmetric energy exchange interactions, also known as Hatano-Nelson type couplings, enable the study of non-Hermitian physics and associated phenomena like the non-Hermitian skin…
Dynamic Phase Enabled Topological Mode Steering in Composite Su-Schrieffer-Heeger Waveguide Arrays
Min Tang, Chi Pang, Christian N. Saggau +10
Topological boundary states localize at interfaces whenever the interface implies a change of the associated topological invariant encoded in the geometric phase. The generically p…
