Quantum Monte Carlo

Science, 1986
An outline of a random walk computational method for solving the Schrödinger equation for many interacting particles is given, together with a survey of results achieved so far and of applications that remain to be explored. Monte Carlo simulations can be used to calculate accurately the bulk properties of the light elements hydrogen, helium, and ...

Linear-Scaling Quantum Monte Carlo Calculations

Physical Review Letters, 2001
Abstract This study demonstrates linear scaling with system size in fixednode diffusion QMC calculations with pseudopotentials for carbon fullerenes and for hydrogenated silicon clusters with nearly 1000 valence electrons. The range covered is C20 to C18o and SiH4 to Si211H140, The calculations were carried out with standard ...

Quantum Monte Carlo Simulations

AIP Conference Proceedings, 2009
In these lecture notes we present an introduction to modern quantum Monte Carlo methods for strongly correlated quantum lattice models. After an introduction to classical Monte Carlo methods we will present the loop algorithm, directed loop algorithm, worm algorithm, Wang‐Landau sampling for quantum systems, and continuous‐time algorithms for quantum ...

Quantum Monte Carlo

1987
Monte Carlo methods allow us to explore the properties of interacting many-body quantum systems. Here we discuss what we have learned about (1) the 2-D XXZ spin-1/2 system and (2) superconductivity near a Van Hove singularity from simulations; and comment on future needs and prospects.

Quantum Monte Carlo

2007
Abstract Monte Carlo methods are a class of computational algorithms for simulating the behavior of a wide range of various physical and mathematical systems (with many variables). Their utility has increased with general availability of fast computers, and new applications are continually forthcoming.

Noncovalent Interactions by Quantum Monte Carlo

Chemical Reviews, 2016
Quantum Monte Carlo (QMC) is a family of stochastic methods for solving quantum many-body problems such as the stationary Schrödinger equation. The review introduces basic notions of electronic structure QMC based on random walks in real space as well as its advances and adaptations to systems with noncovalent interactions.

Rydberg states with quantum Monte Carlo

The Journal of Chemical Physics, 2006
Calculations on Rydberg states are performed using quantum Monte Carlo methods. Excitation energies and singlet-triplet splittings are calculated for two model systems, the carbon atom (P3 and P1) and carbon monoxide (Σ1 and Σ3). Kohn-Sham wave functions constructed from open-shell localized Hartree-Fock orbitals are used as trial and guide functions ...
