Autor: Elisabeth Galopin, Tomoki Ozawa, P. St-Jean, Alberto Amo, Isabelle Sagnes, Jacqueline Bloch, Aristide Lemaître, L. Le Gratiet, V. Goblot

Publikováno v: Nature Photonics. 11:651-656

Topology describes properties that remain unaffected by smooth distortions. Its main hallmark is the emergence of edge states localized at the boundary between regions characterized by distinct topological invariants. This feature offers new opportun

Conduction through materials crucially depends on how ordered they are. Periodically ordered systems exhibit extended Bloch waves that generate metallic bands, whereas disorder is known to limit conduction and localize the motion of particles in a me

Phase frustration in periodic lattices is responsible for the formation of dispersionless flat bands. The absence of any kinetic energy scale makes flat band physics critically sensitive to perturbations and interactions. We report here on the experi

We demonstrate how to tailor the losses of nonlinear cavities in order to suppress their reflection and enhance their non-reciprocal transmission. We derive analytical expressions predicting the existence of zero-reflection channels in single and cou

Modulational instabilities play a key role in a wide range of nonlinear optical phenomena, leading e.g. to the formation of spatial and temporal solitons, rogue waves and chaotic dynamics. Here we experimentally demonstrate the existence of a modulat

Phase-Controlled Bistability of a Dark Soliton Train in a Polariton Fluid

Autor: Alberto Amo, Isabelle Sagnes, V. Goblot, Elisabeth Galopin, Jacqueline Bloch, Iacopo Carusotto, Hai Son Nguyen, Aristide Lemaître

Publikováno v: Physical review letters. 117(21)

We use a one-dimensional polariton fluid in a semiconductor microcavity to explore the rich nonlinear dynamics of counter-propagating interacting Bose fluids. The intrinsically driven-dissipative nature of the polariton fluid allows to use resonant p
