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 fa…
Hybrid confinement techniques for polariton simulators
Johannes Düreth, Philipp Gagel, David Laibacher +13
Exciton-polariton III-V semiconductor microcavities provide a robust platform for emulating complex Hamiltonians, enabling topological photonics and quantum simulation for advanced…
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…
Direct experimental access to the bulk band inversion in a topological metamaterial
Simon Widmann, Johannes Düreth, Siddhartha Dam +9
Topological phases in exciton-polaritons and other metamaterial platforms have attracted significant attention due to their flexibility as Hamiltonian simulators. In previous works…
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…
Enwrapped Perylene Bisimide Enables Room Temperature Polariton Lasing and Photonic Lattices
Dominik Horneber, Johannes Düreth, Tim Schembri +5
Perylene bisimides (PBIs) are organic dyes with photoluminescence quantum yields (PLQY) close to unity in solution and great thermal and photo-chemical stability. These features al…
