Long-time Anderson Localization for the Nonlinear quasi-periodic Schrödinger Equation on $\mathbb Z^d$
Published 27 Sep 2023 in math-ph, math.AP, math.DS, and math.MP | (2309.15706v1)
Abstract: Using a Birkhoff normal form transform to impede mode transfer in a finite "barrier", we prove localization of arbitrary $\ell2$ data for polynomially long time for the nonlinear quasi-periodic Schr\"odinger equation on $\mathbb Zd$.
