This topical review describes the methodology of continuum variational and diffusion
quantum Monte Carlo calculations. These stochastic methods are based on many-body …

One always looks for a simplified technique and desirable formalism, to solve the
Hamiltonian, and to find the wave function, energy, etc, of a many-body system. The lowest …

We introduce a new stochastic method for calculating ground-state properties of quantum
systems. Segments of a Langevin random walk guided by a trial wave function are subject to …

The correlation energy of the homogeneous three-dimensional interacting electron gas is
calculated using the variational and fixed-node diffusion Monte Carlo methods, with trial …

Correlations in the nuclear wave-function beyond the mean-field or Hartree-Fock
approximation are very important to describe basic properties of nuclear structure. Various …

This book is devoted to the description of Bosonic and Fermionic systems: metallic clusters;
quantum dots, wires, rings and molecules; trapped Fermi and Bose atoms; liquid drops of …

We justify and evaluate backflow three-body wave functions for a two-component system of
electrons and protons. Based on the generalized Feynman-Kacs formula, many-body …

We show how a ground-state trial wave function of a Fermi liquid can be systematically
improved by introducing a sequence of renormalized coordinates through an iterative …

The size of the population of random walkers required to obtain converged estimates in
diffusion Monte Carlo (DMC) increases dramatically with system size. We illustrate this by …

The application of the diffusion Monte Carlo method to a strongly interacting Fermi system as
normal liquid 3 He is explored. We show that the fixed-node method together with the …
