چکیده مقاله:
In this article, an efficient numerical technique for solving the two-dimensional time-dependent Schrodinger equation is presented. At first, we employ the meshlesslocal Petrov-Galerkin (MLPG) method based on a local weak formulation to construct a system of discretized equations and then the solution of time-dependentSchrodingerequation will be approximated. We use the Moving Kriging (MK) interpolation insteadof Moving least Square (MLS) approximation to construct the MLPG shape functionsand hence the Heaviside step function is chosen to be the test function. In this method,no mesh is needed neither for integration of the local weak form nor construction of theshape functions. So, the MLPG is truly a meshless method. Several numerical examplesare presented and the results are compared to their analytical and RBFsolutions to illustrate the accuracy and capability of this algorithm.
