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…

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…
