Simplified title focusing on cubic nonlinear Schrödinger equation with rough potential
This paper studies the cubic nonlinear Schrödinger equation with a spatially rough potential, which is key to modeling nonlinear Anderson localization where waves become localized under a rough potential. The work provides new optimal well-posedness analysis characterizing how the potential regularity impacts the solution regularity. Sharp ill-posedness results indicate the minimum potential regularity for solvability. A new efficient numerical method is proposed and analyzed, with simulations confirming the theoretical results and showcasing superior accuracy over existing methods.
