Path Integral Monte Carlo Calculation of the Momentum Distribution of the Homogeneous Electron Gas at Finite Temperature
B. Militzer, E. L. Pollock, D. M. Ceperley
Path integral Monte Carlo (PIMC) simulations are used to calculate the momentum distribution of the homogeneous electron gas at finite temperature. This is done by calculating the…
Multi-spin exchange model the near melting transition of the 2D Wigner crystal
B. Bernu, D. M. Ceperley
The low temperature properties of fermionic solids are governed by spin exchanges. Near the melting transition, the spin-exchange energy increases as well as the relative contribut…
Metropolis Methods for Quantum Monte Carlo Simulations
D. M. Ceperley
Since its first description fifty years ago, the Metropolis Monte Carlo method has been used in a variety of different ways for the simulation of continuum quantum many-body system…
Backflow Correlations for the Electron Gas and Metallic Hydrogen
M. Holzmann, D. M. Ceperley, C. Pierleoni +1
We justify and evaluate backflow-threebody wavefunctions for a two component system of electrons and protons. Based on the generalized Feynman-Kacs formula, many-body perturbation…
