Coupled Electron Ion Monte Carlo Calculations of Atomic Hydrogen

Markus Holzmann, Carlo Pierleoni, David M. Ceperley

We present a new Monte Carlo method which couples Path Integral for finite temperature protons with Quantum Monte Carlo for ground state electrons, and we apply it to metallic hydr…

Ring exchanges and the supersolid phase of 4He

D. M. Ceperley, B. Bernu

Using Path Integral Monte Carlo we calculate exchange frequencies in bulk hcp 4He as atoms undergo ring exchange. We fit the frequencies to a lattice model and examine whether such…

Accurate, efficient and simple forces with Quantum Monte Carlo methods

Simone Chiesa, David Ceperley, Shiwei Zhang

Computation of ionic forces using quantum Monte Carlo methods has long been a challenge. We introduce a simple procedure, based on known properties of physical electronic densities…

The Magnetic Ordering of the 3d Wigner Crystal

Ladir Candido, B. Bernu, D. M. Ceperley

Using Path Integral Monte Carlo, we have calculated exchange frequencies as electrons undergo ring exchanges of 2, 3 and 4 electrons in a ``clean'' 3d Wigner crystal (bcc lattice)…
