Fingerprints of the local moment formation and its Kondo screening in the generalized susceptibilities of many-electron problems
Patrick Chalupa, Thomas Schäfer, Matthias Reitner +3
We identify the precise hallmarks of the local magnetic moment formation and its Kondo screening in the frequency structure of the generalized charge susceptibility. The sharpness…

Attractive effect of a strong electronic repulsion -- the physics of vertex divergences
M. Reitner, P. Chalupa, L. Del Re +4
While the breakdown of the perturbation expansion for the many-electron problem has several formal consequences, here we unveil its physical effect: Flipping the sign of the effect…
