  7. Finite element solution of the S-limit Schrodinger equation of helium

    Keller, John WilliamTexas Tech University1979

    The Schroedinger equation, for all but the simplest systems, is an elliptic partial differential equation. Almost every method of solution is based on the expansion of the unknown solution in terms of a set of known global functions. Only a few calculations, using strictly numerical techniques …

    Lopez Rios, PabloUniversity of Cambridge2016

    Quantum Monte Carlo (QMC) methods are a class of stochastic techniques that can be used to compute the properties of electronic systems accurately from first principles. This thesis is mainly concerned with the development of trial wave functions for QMC. An extension of the backflow transformation …
