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…

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)…
