Dual-fermion approach to interacting disordered fermion systems
S. -X. Yang, P. Haase, H. Terletska +4
We generalize the recently introduced dual fermion (DF) formalism for disordered fermion systems by including the effect of interactions. For an interacting disordered system the c…
Effective Cluster Typical Medium Theory for Diagonal Anderson Disorder Model in One- and Two-Dimensions
Chinedu E. Ekuma, Hanna Terletska, Zi Yang Meng +4
We develop a cluster typical medium theory to study localization in disordered electronic systems. Our formalism is able to incorporate non-local correlations beyond the local typi…
Mean-field embedding of the dual fermion approach for correlated electron systems
S. -X. Yang, H. Terletska, Z. Y. Meng +2
To reduce the rapidly growing computational cost of the dual fermion lattice calculation with increasing system size, we introduce two embedding schemes. One is the real fermion em…
