Description
Summary:The authors present a new approach for calculations of the electronic structure of atoms and molecules. The main features are a functional-integral formulation on a lattice in space and imaginary time, renormalization-group transformations which increase lattice spacings to reduce the number of degrees of freedom, perturbation-theory treatments of core electrons, and a Monte Carlo technique using the Langevin equation for nonperturbative calculations of valence-electron properties at low temperatures.
