I would be interested, too: to be more precise, is there a way of interfacing
Abinit with, for instance, a Monte Carlo code, in order to calculate with
Abinit the energy ab initio and let the code do the rest?

More in depth: is there a way of doing "coarser" calculation with Abinit in
order to save time? Not only using lower cutoffs, but also perhaps applying
perturbation theory in some way if the configurations differ only slightly
from one another.

BTW: are there developments on the Car-Parrinello branch of the code?

Thanks, regards

Silvio a Beccara
