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…

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…

Interfacial effects revealed by ultrafast relaxation dynamics in BiFeO/YBaCuO bilayers
D. Springer, Saritha K. Nair, Mi He +6
The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic BiFeO (BFO) and superconducting YBaCuO$_{7…
