We present and compare several approaches to implement the classical transparent boundary condition into finite difference and finite element discretizations. We present in detail the approaches of the authors and describe briefly alternative ideas pointing out the relations between these works. We conclude with several numerical examples from different application areas to compare the presented techniques. We mainly focus on the one-dimensional problem but also touch upon the situation in two space dimensions and the cubic nonlinear case.en510 MathematikSchrödinger equationtransparent boundary conditionsdiscrete convolutionunbounded domainfinite difference schemesfinite elementsResearch Paper
