    Notes: Abstract: We evaluate the short time Green function by a series expansion of the exponent. The resulting expression allows the computation of the energy eigenvalues and eigenvectors of a quantum system with a very high precision. As an example, we show the comparison between the numerical results and the analytical solutions for harmonic and multi-well potentials both in one and two dimensions.
