The quantum mechanics of two electrons atoms, as suggested by E. A. Hylleraas in the period between 1928-1930, is discussed in the present work. Hylleraas introduced explicit correlations in the wavef
We demonstrate the rapid convergence of an iterative approximation that enables the Crank-Nicolson method for solving partial differential equations to be parallelized with arbitrarily small error, so

Abstract In this manuscript, we solve an asymmetric 2D problem for a long cylinder. The surface is assumed to be traction free and subjected to an asymmetric temperature distribution. A direct approac
Abstract Two codes to evaluate the real zeros (j_(v,s)) of the Bessel functions of the first kind J_v (x) for real orders v are presented. The codes are based on a Newton-Raphson iteration over the
