Benchmarks and results of the two-band Hubbard model from the Gutzwiller conjugate gradient minimization theory
Zhuo Ye, Feng Zhang, Yong-Xin Yao +2
Ground-state properties, such as energies and double occupancies, of a one-dimensional two-band Hubbard model are calculated using a first principles Gutzwiller conjugate gradient…

Ground state properties of one-dimensional and two-dimensional Hubbard model from Gutzwiller conjugate gradient minimization theory
Zhuo Ye, Feng Zhang, Yong-Xin Yao +2
We introduce Gutzwiller conjugate gradient minimization (GCGM) theory, an ab initio quantum many-body theory for computing the ground-state properties of infinite systems. GCGM use…
