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…
Evolution of the Superconductivity Dome in the two dimensional Hubbard Model
Kuang-Shing Chen, Zi Yang Meng, Shu-Xiang Yang +3
In a recent publication [Chen et al., Phys. Rev. B 86, 165136 (2012)], we identified a line of Lifshitz transition points separating the Fermi liquid and pseudogap regions in the h…
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…
Unconventional superconductivity on the triangular lattice Hubbard model
Kuang Shing Chen, Zi Yang Meng, Unjong Yu +3
Using large-scale dynamical cluster quantum Monte Carlo simulations, we explore the unconventional superconductivity in the hole-doped Hubbard model on the triangular lattice. Due…
