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…

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…

Propagative oscillations in co-directional polariton waveguide couplers

J. Beierlein, E. Rozas, O. A. Egorov +12

We report on novel exciton-polariton routing devices created to study and purposely guide light-matter particles in their condensate phase. In a co-directional coupling device, two…

Exciton-polaritons in flatland: Controlling flatband properties in a Lieb lattice

Tristan H. Harder, Oleg A. Egorov, Johannes Beierlein +7

In recent years, novel two-dimensional materials such as graphene, bismuthene and transition-metal dichalcogenides have attracted considerable interest due to their unique physical…
