Abstract:

Based on the semi-discrete artificial boundary condition introduced by Ji, Yang, and Antoine [Comput. Phys. Commun. 222 (2018), pp. 84–93] for the two-dimensional free Schrödinger equation in a computational rectangular domain, we propose to analyze the stability and convergence rate with respect to time of the resulting full scheme. We prove that the global scheme is $L^{2}$-stable and that the accuracy is second-order in time, confirming then the numerical results reported by Ji et al. (2018).
