Measuring non-Abelian quantum geometry and topology in a multi-gap photonic lattice
Martin Guillot, Cédric Blanchard, Martina Morassi +8
Recent discoveries in semi-metallic multi-gap systems featuring band singularities have galvanized enormous interest in particular due to the emergence of non-Abelian braiding prop…
Observation of KPZ universal scaling in a one-dimensional polariton condensate
Quentin Fontaine, Davide Squizzato, Florent Baboux +14
Revealing universal behaviors is a hallmark of statistical physics. Phenomena such as the stochastic growth of crystalline surfaces, of interfaces in bacterial colonies, and spin t…
Chiral emission induced by optical Zeeman effect in polariton micropillars
B. Real, N. Carlon Zambon, P. St-Jean +7
The low sensitivity of photons to external magnetic fields is one of the major challenges for the engineering of photonic lattices with broken time-reversal symmetry. Here we show…
Topological gap solitons in a 1D non-Hermitian lattice
N. Pernet, P. St-Jean, D. D. Solnyshkov +13
Nonlinear topological photonics is an emerging field aiming at extending the fascinating properties of topological states to the realm where interactions between the system constit…
Semi-Dirac Transport and Anisotropic Localization in Polariton Honeycomb Lattices
B. Real, O. Jamadi, M. Milićević +11
Compression dramatically changes the transport and localization properties of graphene. This is intimately related to the change of symmetry of the Dirac cone when the particle hop…
Direct observation of photonic Landau levels and helical edge states in strained honeycomb lattices
O. Jamadi, E. Rozas, G. Salerno +9
We report the realization of a synthetic magnetic field for photons and polaritons in a honeycomb lattice of coupled semiconductor micropillars. A strong synthetic field is induced…
Parametric instability in coupled nonlinear microcavities
N. Carlon Zambon, S. R. K. Rodriguez, A. Lemaitre +7
We report the observation of a parametric instability in the out-of-equilibrium steady state of two coupled Kerr microresonators coherently driven by a laser. Using a resonant exci…
Nonlinear Polariton Fluids in a Flatband Reveal Discrete Gap Solitons
V. Goblot, B. Rauer, F. Vicentini +10
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 sen…
Tilted and type-III Dirac cones emerging from flat bands in photonic orbital graphene
M. Milićević, G. Montambaux, T. Ozawa +6
The extraordinary electronic properties of Dirac materials, the two-dimensional partners of Weyl semimetals, arise from the linear crossings in their band structure. When the dispe…
Lasing in optically induced gap states in photonic graphene
M. Milićević, O. Bleu, D. D. Solnyshkov +7
We report polariton lasing in localised gap states in a honeycomb lattice of coupled micropillars. Localisation of the modes is induced by the optical potential created by the exci…
