Many-body perturbation theory and non-perturbative approaches: the screened interaction as key ingredient
Walter Tarantino, Bernardo S. Mendoza, Pina Romaniello +2
Many-body perturbation theory is often formulated in terms of an expansion in the dressed instead of the bare Green's function, and in the screened instead of the bare Coulomb inte…

The self-consistent Dyson equation and self-energy functionals: failure or new opportunities?
Walter Tarantino, Pina Romaniello, J. A. Berger +1
Perturbation theory using self-consistent Green's functions is one of the most widely used approaches to study many-body effects in condensed matter. On the basis of general consid…
