Advances in quantum Monte Carlo techniques for nonrelativistic manybody systems
June 24  August 2, 2013
PURPOSE
Setting up an occasion for scientists from the three communities of
quantum chemistry, condensed matter physics, and nuclear physics to
gather and exchange expertise and progress in all the aspects of
Quantum Monte Carlo techniques for continuum systems that go beyond
the mere application of standard algorithms. In particular, our main
objectives include:

Understanding the level of progress that has been already reached,
and that is reachable in the future, towards controllable accuracy in
manyfermion calculations. This implies the building of a
comprehensive understanding of all the approximations (the standard
fixednode, but also the fixedphase approximation for the case of DMC
calculations, constrainedpath approximations for pathbased
algorithms and systematic uncertainties in lattice methods) as well as
the possible ways of going beyond them, by means of more efficient
transient calculations.

Promoting a definition of a standard level of accuracy of QMC
calculations that can be applied across different research fields.

Defining a meaningful benchmark problem to be used in order to
systematically compare the different methods and approximations, both
for ground state and finite temperature calculations.
