Geometric Optics for One-Dimensional Schrödinger-Poisson System
This paper considers a family of Schrödinger-Poisson system in one dimension, whose initial data oscillates so that a caustic appears. By using the Lagrangian integrals, the authors obtain a uniform description of the solution outside the caustic, and near the caustic.
