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."],"identifier":["https://research-explorer.ista.ac.at/record/1419"],"type":["info:eu-repo/semantics/article","doc-type:article","text","http://purl.org/coar/resource_type/c_6501"],"language":["eng"],"date":["2016"],"title":["Gutzwiller wave function for finite systems: Superconductivity in the Hubbard model"],"relation":["info:eu-repo/semantics/altIdentifier/doi/10.1088/0953-8984/28/17/175701","info:eu-repo/grantAgreement/EC/FP7/291734"],"publisher":["IOP Publishing Ltd."],"source":["Tomski A, Kaczmarczyk J.
