Scientists solve decades-old 2D physics puzzle — Chaotic growth in a 2D quantum system obeys statistical laws

Researchers at the University of Würzburg experimentally showed that chaotic growth in a 2D quantum polariton system follows KPZ statistics.

The finding extends prior experimental proof of the KPZ equation beyond one-dimensional systems into a more realistic 2D setting.

It helps settle a decades-old physics question and strengthens how scientists model non-equilibrium growth processes.

The study was published in Science.
