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…

Exciton-polariton III-V semiconductor microcavities provide a robust platform for emulating complex Hamiltonians, enabling topological photonics and quantum simulation for advanced…
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…
An electrically pumped topological polariton laser
Philipp Gagel, Oleg A. Egorov, Franciszek Dzimira +9
With a seminal work of Raghu and Haldane in 2008, concepts of topology have been successfully introduced in a wide range of optical systems, emulating specific lattice Hamiltonians…
Accuracy Evaluation of Touch Tasks in Commodity Virtual and Augmented Reality Head-Mounted Displays
Daniel Schneider, Verena Biener, Alexander Otte +9
An increasing number of consumer-oriented head-mounted displays (HMD) for augmented and virtual reality (AR/VR) are capable of finger and hand tracking. We report on the accuracy o…
Bloch Oscillations of Hybrid Light-Matter Particles in a Waveguide Array
Johannes Beierlein, Oleg. A. Egorov, Tristan H. Harder +6
Bloch oscillations are a phenomenon well known from quantum mechanics where electrons in a lattice experience an oscillatory motion in the presence of an electric field gradient. H…
Kagome Flatbands for Coherent Exciton-Polariton Lasing
Tristan H. Harder, Oleg A. Egorov, Constantin Krause +7
Kagome lattices supporting Dirac cone and flatband dispersions are well known as a highly frustrated, two-dimensional lattice system. Particularly the flatbands therein are attract…
Pen-based Interaction with Spreadsheets in Mobile Virtual Reality
Travis Gesslein, Verena Biener, Philipp Gagel +5
Virtual Reality (VR) can enhance the display and interaction of mobile knowledge work and in particular, spreadsheet applications. While spreadsheets are widely used yet are challe…
