We study the characteristic timescales of the fluctuating local moments in Hund's metal systems for different degrees of correlation. By analyzing the dynamical spin susceptibility in the real-time domain, we determine the timescales controlling oscillation and damping of on-site fluctuations-a crucial factor for the detection of local moments with different experimental probes. We apply this procedure to different families of iron pnictides or chalcogenides, explaining the material trend in…

Resistivity Exponents in 3D Dirac Semimetals From Electron-Electron Interaction.

This work studies the resistivity of three-dimensional semimetals with linear dispersion in the presence of on-site electron-electron interaction to yield a natural explanation for the hitherto not understood large exponents characterizing the temperature dependence of transport experiments on various topological semimetal.

Osmates on the Verge of a Hund's-Mott Transition: The Different Fates of NaOsO_{3} and LiOsO_{3}.

It is shown that the cooperative action of intraorbital repulsion and Hund's exchange becomes the dominant physical mechanism in these materials if their t_{2g} shell is half filled.

A comprehensive overview of the different approaches which have been recently developed and applied to identify the dominant two-particle scattering processes controlling the shape of the one-particles spectral functions and, in some cases, of the physical response of the system.

Itinerancy-enhanced quantum fluctuation of magnetic moments in iron-based superconductors.

Interestingly, the underlying mechanism is shown to be an intrapocket nesting-associated long-range coupling rather than the previously believed ferromagnetic double-exchange effect, which challenges the validity of ferromagnetically compensated first-neighbor coupling reported from short-range fitting to the experimental dispersion.

Janus-faced influence of Hund's rule coupling in strongly correlated materials.

A concise classification of 3d and 4d transition-metal oxides is proposed within which the ubiquitous occurrence of strong correlations in Ru- and Cr-based oxides, as well as the recently measured high Néel temperatures in Tc-based perovskites are naturally explained.
