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…
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…
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…
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…
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…
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…
