Large effects of subtle electronic correlations on the energetics of vacancies in alpha-Fe
Pascal Delange, Thomas Ayral, Sergei I. Simak +4
We study the effect of electronic Coulomb correlations on the vacancy formation energy in paramagnetic alpha-Fe within ab initio dynamical mean-field theory. The calculated value f…

Mott physics and collective modes: an atomic approximation of the four-particle irreducible functional
Thomas Ayral, Olivier Parcollet
We discuss a generalization of the dynamical mean field theory (DMFT) for strongly correlated systems close to a Mott transition based on a systematic approximation of the fully ir…
