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…

Characteristic Timescales of the Local Moment Dynamics in Hund's-metals

C. Watzenböck, M. Edelmann, D. Springer +2

We study the characteristic time scales of the fluctuating local moments in Hund's metal systems for different degrees of correlation. By analyzing the dynamical spin susceptibilit…

Coulomb Engineering of two-dimensional Mott materials

Erik G. C. P. van Loon, Malte Schüler, Daniel Springer +3

Two-dimensional materials can be strongly influenced by their surroundings. A dielectric environment screens and reduces the Coulomb interaction between electrons in the two-dimens…

Interplay between local response and vertex divergences in many-fermion systems with on-site attraction

D. Springer, P. Chalupa, S. Ciuchi +2

We investigate the divergences appearing in the two-particle irreducible vertex functions of many-fermion systems with attractive on-site interactions. By means of dynamical mean-f…

Osmates on the verge of a Hund's-Mott transition: The different fates of NaOsO and LiOsO

Daniel Springer, Bongjae Kim, Peitao Liu +6

We clarify the origin of the strikingly different spectroscopic properties of the chemically similar compounds NaOsO and LiOsO. Our first-principle many-body analysis demon…
