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…
Room temperature topological polariton laser in an organic lattice
Marco Dusel, Simon Betzold, Tristan. H. Harder +7
Interacting bosonic particles in artificial lattices have proven to be a powerful tool for the investigation of exotic phases of matter as well as phenomena resulting from non-triv…
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…
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.…
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…
