The DE-GWF method works on the level of the full GWF and in the thermodynamic limit. Here, we consider a finite-size system to study the accuracy of the results as a function of the system size (which is practically unrestricted). We show that the finite-size scaling used, e.g. in the variational Monte Carlo method can lead to significant, uncontrolled errors. The presented research is the first step towards applying the DE-GWF method in studies of inhomogeneous situations, including systems with impurities, defects, inhomogeneous phases, or disorder.","lang":"eng"}],"month":"03","article_number":"175701","language":[{"iso":"eng"}],"scopus_import":"1","doi":"10.1088/0953-8984/28/17/175701","date_created":"2018-12-11T11:51:55Z","quality_controlled":"1"}
