A dual fermion approach for disordered interacting systems: Application to the Anderson-Hubbard model
ORAL
Abstract
We have recently generalized the dual fermion approach to the disordered interacting fermionic systems. Here it is applied to the Anderson-Hubbard model at finite temperature. With both disorder and Coulomb interaction treated on equal footing, and non-local correlations taken into account, we analyze the underlying competing physics related to metal-insulation transitions and anti-ferromagnetic transition by looking into both one- and two-particle quantities.
