Solving RPA Eigenvalue Equation in Real-Space

摘要

We present a computational method to solve RPA eigenvalue equation employing a uniform grid representation in the three-dimensional Cartesian coordinate. The conjugate gradient method, an iterative method for a generalized eigenvalue problem, is used for this purpose. We apply the present method to Hartree-Fock +RPA calculation with BKN-like interaction and Skyrme interaction.
