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…
Topological Floquet interface states in optical fibre loops
Arstan Bisianov, Andre Muniz, Ulf Peschel +1
We experimentally observe a coexisting pair of topological anomalous Floquet interface states in a (1+1)-dimensional Discrete Photon Walk. We explicitly verify the robustness of th…
Superfluidity of Light and its Break-Down in Optical Mesh Lattices
Martin Wimmer, Monika Monika, Iacopo Carusotto +2
Hydrodynamic phenomena can be observed with light thanks to the analogy between quantum gases and nonlinear optics. In this Letter, we report an experimental study of the superflui…
Coherent topological polariton laser
Tristan H. Harder, Meng Sun, Oleg A. Egorov +9
Topological concepts have been applied to a wide range of fields in order to successfully describe the emergence of robust edge modes that are unaffected by scattering or disorder.…
Impact of the energetic landscape on polariton condensates propagation along a coupler
E. Rozas, J. Beierlein, A. Yulin +10
Polariton condensates propagation is strongly dependent on the particular energy landscape the particles are moving upon, in which the geometry of the pathway laid for their moveme…
