原文开头
Observation of Kardar-Parisi-Zhang universal scaling in two dimensions Simon Widmann1†, Siddhartha Dam1*†, Johannes Düreth1, Christian G. Mayer1, Romain Daviet2, Carl Philipp Zelle2,3, David Laibacher1, Monika Emmerling1, Martin Kamp1, Sebastian Diehl2, Simon Betzold1, Sebastian Klembt1,4, Sven Höfling1* Equilibrium and nonequilibrium states of matter can exhibit fundamentally different behavior. A key example is the Kardar-Parisi-Zhang universality class in two spatial dimensions (2D KPZ), where microscopic deviations from equilibrium give rise to macroscopic scaling laws without equilibrium counterparts. Although extensively studied theoretically, experimental evidence of 2D KPZ scaling has remained limited to interface growth. Here, we report the observation of KPZ universal scaling in 2D exciton-polariton condensates—quantum fluids of light that inherently break equilibrium conditions. …
