On Optimal Convergence Rates for the Nonlinear Schrödinger Equation with a Wave Operator via Localized Orthogonal Decomposition

This paper introduces a Localized Orthogonal Decomposition (LOD) method for the two-dimensional time-dependent nonlinear Schrödinger equation with a wave operator, proving that it preserves conservation laws, ensures unique solutions, and achieves unconditional optimal-order superconvergent LpL^p error estimates, which are further validated by numerical simulations.
