Approximating a Wavefunction as an Unconstrained Sum of Slater Determinants
Gregory Beylkin, Martin J. Mohlenkamp, Fernando Pérez
The wavefunction for the multiparticle Schrödinger equation is a function of many variables and satisfies an antisymmetry condition, so it is natural to approximate it as a sum of…

Fast Adaptive Algorithms in the Non-Standard Form for Multidimensional Problems
Gregory Beylkin, Vani Cheruvu, Fernando Pérez
We present a fast, adaptive multiresolution algorithm for applying integral operators with a wide class of radially symmetric kernels in dimensions one, two and three. This algorit…
