Synchronization critical dynamics in higher spatial dimensions

Investigate the nonequilibrium critical dynamics of synchronization in oscillator lattices for spatial dimensions d>1, determining the emergent universality classes, scaling exponents, and fluctuation statistics, and whether the KPZ/EW phenomenology and crossovers found in one dimension persist in higher dimensions.

Background

The present work establishes one-dimensional universal behavior and crossovers linking synchronization dynamics to KPZ/EW universality classes under different types of randomness.

The authors explicitly note that higher-dimensional cases have not yet been studied and point to phenomenological similarities and prior indications suggesting that a similar program might be feasible, highlighting the open direction to extend and test the framework in d>1.

While the case of higher dimensions has not yet been studied, as far as we know, there are some indications showing that a similar analysis might be performed ; see also the phenomenological similarities between the profiles arising from the columnar KPZ equation in two dimensions and the phase interfaces displayed in Ref..
