Abstract: L18.00009 : Divergences of the irreducible vertex functions in correlated metallic systems: Insights from the Anderson Impurity Model
12:51 PM–1:03 PM
(College de France)
underlying physics is greatly simplified by the absence of low-energy quasiparticle excitations. In this respect, our numerical calculations for the AIM, as well as their comparison with the corresponding results for the Hubbard model, allow us to clarify several open questions about the origin and the properties of vertex divergences occurring in a more interesting context, the correlated metallic regime at low-temperatures.
