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…
