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…
