We formulate FLEX+DMFT in a systematic way starting from a Luttinger-Ward functional, and apply it to study the d -wave superconductivity in the two-dimensional repulsive Hubbard model. The critical temperature (T) curve obtained in the FLEX+DMFT exhibits a dome structure as a function of the...
We propose to combine the dynamical mean field theory (DMFT) with the fluctuation exchange approximation (FLEX) to investigate strongly correlated systems and especially to obtain a phase diagram for d-wave superconductors such as the cuprates. The DMFT+FLEX method, which can also be viewed as ...
A self-consistent DFT + DMFT scheme in the projector augmented wave method: applications to cerium, Ce2O3and Pu2O3with the Hubbard I solver and comparison ... An implementation of full self-consistency over the electronic density in the DFT?+?DMFT framework on the basis of a plane wave鈥...
Based on the analysis of the Eliashberg equation, we found that a pairing mechanism exploiting an incipient band discussed in the previous studies is still valid even with the local vertex corrections coming from the DMFT part of the self-energy....
