Momentum-space finite-size corrections for Quantum-Monte-Carlo calculations
R. Gaudoin, I. G. Gurtubay, J. M. Pitarke
Extended solids are frequently simulated as finite systems with periodic boundary conditions, which due to the long-range nature of the Coulomb interaction may lead to slowly decay…
Benchmark Quantum Monte Carlo calculations of the ground-state kinetic, interaction, and total energy of the three-dimensional electron gas
I. G. Gurtubay, R. Gaudoin, J. M. Pitarke
We report variational and diffusion Quantum Monte Carlo ground-state energies of the three-dimensional electron gas using a model periodic Coulomb interaction and backflow correcti…
An efficient method for the Quantum Monte Carlo evaluation of the static density-response function of a many-electron system
R. Gaudoin, J. M. Pitarke
In a recent Letter we introduced Hellmann-Feynman operator sampling in diffusion Monte Carlo calculations. Here we derive, by evaluating the second derivative of the total energy,…
Hellman-Feynman operator sampling in Diffusion Monte Carlo calculations
R. Gaudoin, J. M. Pitarke
Diffusion Monte Carlo (DMC) calculations typically yield highly accurate results in solid-state and quantum-chemical calculations. However, operators that do not commute with the H…
Quantum Monte Carlo modelling of the spherically averaged structure factor of a many-electron system
R. Gaudoin, J. M. Pitarke
The interaction and exchange-correlation contributions to the ground-state energy of an arbitrary many-electron system can be obtained from a spherical average of the wavevector-de…
An inhomogeneous and anisotropic Jastrow function for non-uniform many-electron systems
A. Garcia-Lekue, M. Nekovee, J. M. Pitarke +1
Quantum Monte Carlo simulations of interacting electrons in solids often use Slater-Jastrow trial wave functions. The Jastrow function takes into account correlations between pairs…
