Accessing Chern Numbers From Bloch Eigenstates Singularities
Rajesh Asapanna, Rabih El Sokhen, Paolo Aceto +7
We propose two methods to extract the Chern numbers of the Bloch bands of a two dimensional insulator, and apply them to a photonic lattice experiment. These two methods require th…
Crossing over universal scaling laws in two-dimensional driven dissipative condensates
Q. Fontaine, F. Helluin, M. Escalera +8
In low dimensional systems, fluctuations are enhanced and prevent the spontaneous breaking of continuous symmetries. As a result, spatial and temporal correlation functions decay a…
Comment on "Observation of Kardar--Parisi--Zhang universal scaling in two dimensions"
J. Bloch, M. Escalera, Q. Fontaine +4
In their paper published in Science 392, 221 (2026), Widmann and collaborators reported interferometry experiments to explore the emission coherence decay of a two-dimensional pola…
Synthetic Polariton Matter in the solid state
Sylvain Ravets
Synthetic materials are obtained by assembling atoms or artificial atoms into regular arrays, thereby forming artificial crystals that offer powerful platforms to emulate and explo…
Emission of time-ordered photon pairs from a coherently-driven Kerr microcavity
Ferdinand Claude, Yueguang Zhou, Sylvain Ravets +8
Weakly-interacting many-body systems possess remarkable quantum properties that are essential components of quantum technologies, and constitute a topic of fundamental interest. He…
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…
All-optical nonlinear phase modulation in open semiconductor microcavities
Fedor A. Benimetskiy, Paul M. Walker, Anthony Ellul +8
We report a significant advancement in ultra low power light-by-light phase modulation using open semiconductor microcavities in the strong light-matter coupling regime. We achieve…
Excitonic oscillator-strength saturation dominates polariton-polariton interactions
Maxime Richard, Irénée Frérot, Sylvain Ravets +8
Exciton-polaritons in semiconductor microcavities exhibit large two-body interactions that, thanks to ever refined nanotechnology techniques, are getting closer and closer to the q…
Phase diagram and universal scaling regimes of two-dimensional exciton-polariton Bose-Einstein condensates
Félix Helluin, Daniela Pinto-dias, Quentin Fontaine +4
Many systems, classical or quantum, closed or open, exhibit universal statistical properties. Exciton-polariton condensates, being intrinsically driven-dissipative, offer a promisi…
Kardar-Parisi-Zhang universality in discrete two-dimensional driven-dissipative exciton polariton condensates
Konstantinos Deligiannis, Quentin Fontaine, Davide Squizzato +5
The statistics of the fluctuations of quantum many-body systems are highly revealing of their nature. In driven-dissipative systems displaying macroscopic quantum coherence, as exc…
Demonstration of a strong Rydberg blockade in three-atom systems with anisotropic interactions
Daniel Barredo, Sylvain Ravets, Henning Labuhn +5
We study the Rydberg blockade in a system of three atoms arranged in different 2D geometries (linear and triangular configurations). In the strong blockade regime, we observe high-…
