Description:
Author(s): Jan Kaczmarczyk, Jozef Spałek, Tobias Schickling, and Jörg Bünemann A systematic diagrammatic expansion for Gutzwiller-wave functions (DE-GWF) is formulated and used for the description of superconducting (SC) ground state in the two-dimensional Hubbard model with electron-transfer amplitudes t (and t ′ ) between nearest (and next-nearest) neighbors. The method is num... [Phys. Rev. B 88, 115127] Published Mon Sep 16, 2013
