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…
Dirac Cones and Room Temperature Polariton Lasing Evidenced in an Organic Honeycomb Lattice
Simon Betzold, Johannes Düreth, Marco Dusel +6
Artificial one- and two-dimensional lattices have emerged as a powerful platform for the emulation of lattice Hamiltonians, the fundamental study of collective many-body effects, a…
Topological Optical Waveguiding of Exciton-Polariton Condensates
Johannes Beierlein, Oleg A. Egorov, Philipp Gagel +9
One-dimensional models with topological non-trivial band structures are a simple and effective way to study novel and exciting concepts in topological photonics. In this work we ar…
