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…
Observation of Kardar-Parisi-Zhang universal scaling in two dimensions
Simon Widmann, Siddhartha Dam, Johannes Düreth +10
Equilibrium and nonequilibrium states of matter can exhibit fundamentally different behavior. A key example is the Kardar-Parisi-Zhang universality class in two spatial dimensions…
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…
