Solving Schrödinger equation by meshless methods

In this paper we apply a numerical meshless scheme for solving one and two dimensional time independent Schr ̈ odinger equation by means of collocation method with Radial Basis Functions interpolants. In particular we approximate the solutions using multiquadrics. The method is tested with some of t...

Descrição
Resumo:In this paper we apply a numerical meshless scheme for solving one and two dimensional time independent Schr ̈ odinger equation by means of collocation method with Radial Basis Functions interpolants. In particular we approximate the solutions using multiquadrics. The method is tested with some of the well-known configurations of Schr ̈ odinger equation and compared with analytical solutions, showing a great accuracy and stability. We also provide some insight on how to use meshless algorithms for obtaining the eigenenergies and wavefunctions of one- and two-dimensional Schrodinger problems.
