Study of the Hubbard model on the triangular lattice using dynamical cluster approximation and dual fermion methods
Hunpyo Lee, Gang Li, Hartmut Monien
We investigate the Hubbard model on the triangular lattice at half-filling using the dynamical cluster approximation (DCA) and dual fermion (DF) methods in combination with continu…

Lattice susceptibility for 2D Hubbard Model within dual fermion method
Gang Li, Hunpyo Lee, Hartmut Monien
In this paper, we present details of the dual fermion (DF) method to study the non-local correction to single site DMFT. The DMFT two-particle Green's function is calculated using…
