Self-consistent Dual Boson approach to single-particle and collective excitations in correlated systems
E. A. Stepanov, E. G. C. P. van Loon, A. A. Katanin +3
We propose an efficient dual boson scheme, which extends the DMFT paradigm to collective excitations in correlated systems. The theory is fully self-consistent both on the one- and…

Thermodynamic consistency of the charge response in dynamical mean-field based approaches
Erik G. C. P. van Loon, Hartmut Hafermann, Alexander I. Lichtenstein +1
We consider the thermodynamic consistency of the charge response function in the (extended) Hubbard model. In DMFT, thermodynamic consistency is preserved. We prove that the static…
