Thermodynamic Stability at the Two-Particle Level

A. Kowalski, M. Reitner, L. Del Re +6

We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…

Rationalizing doping and electronic correlations in LaFeAs

Tommaso Gorni, Diego Florez-Ablan, Luca de' Medici

We compute the electronic properties of the normal state of uncollapsed LaFeAs, taking into account local dynamical correlations by means of slave-spin mean-field+density-f…

Mott Quantum Critical Points at finite doping

Maria Chatzieleftheriou, Alexander Kowalski, Maja Berović +5

Strongly correlated materials often undergo a Mott metal-insulator transition, which is tipically first-order, as a function of control parameters like pressure. Upon doping, rich…

Hund's metal crossover and superconductivity in the 111 family of iron-based superconductors

Pablo Villar Arribi, Luca de' Medici

We study LiFeP, LiFeAs and NaFeAs in their paramagnetic metallic phase including dynamical electronic correlations within a density functional theory + slave-spin mean-field framew…

Enhancement of charge instabilities in Hund's metals by the breaking of rotational symmetry

Maria Chatzieleftheriou, Maja Berović, Pablo Villar Arribi +2

We analyze multi-orbital Hubbard models describing Hund's metals, focusing on the ubiquitous occurrence of a charge instability, signalled by a divergent/negative electronic compre…

Hund's metals, explained

Luca de' Medici

A possible practical definition for a Hund's metal is given, as a metallic phase - arising consistently in realistic simulations and experiments in Fe-based superconductors and oth…
