KPZ dynamics from a variational perspective: potential landscape, time behavior, and other issues

Horacio S Wio, Miguel A Rodríguez, R Gallego +2

The deterministic KPZ equation has been recently formulated as a gradient flow, in a nonequilibrium potential (NEP) \[Φ[h(\mathbf{x},t)]=\int\mathrm{d}\mathbf{x}\left[\fracν{2}(\na…
