Slave-spin mean-field theory, a light and accurate technique to model electronic correlations in Fermi-liquid phases of multi-orbital materials, is pedagogically exposed in this chapter, with a focus on its recent successful application to the physics of Iron-based superconductors. Beside introducing electronic correlations and recalling the Fermi-liquid phenomenology, the manuscript accompanies the step-by-step explanation of the slave-spin technique with a set of useful complements providing… 

Heavy fermions and Hund's metals in iron-based superconductors

Materials where the electrons responsible for the low-energy properties experience strong correlations are today very investigated in search of emerging new phases with surprising and/or useful

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

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

PhD Thesis: Electronic correlations in multiorbital systems

The role of electronic correlations in Condensed Matter is at the heart of various important systems, like magnetic materials, superconductors, topological materials, optical lattices, etc.

Mott transition, magnetic and orbital orders in the ground state of the two-band Hubbard model using variational slave-spin mean field formalism

We study the ground state phase diagram of the degenerate two-band Hubbard model at integer fillings as a function of onsite Hubbard interaction U and Hund’s exchange coupling J. We use a variational

Orbital-selective bad metals due to Hund's rule and orbital anisotropy: A finite-temperature slave-spin treatment of the two-band Hubbard model

We study the finite-temperature properties of the half-filled two-band Hubbard model in the presence of Hund's rule coupling and orbital anisotropy. We use the mean-field treatment of the Z(2)

Hund's metals, explained

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 other materials - with

Accurate modeling of FeSe with screened Fock exchange and Hund metal correlations

We reproduce the electronic properties of FeSe in the high-temperature phase within an ab initio framework that includes screened Fock exchange and local dynamical correlations. We robustly capture

Constraints on the total coupling strengthto bosons in the iron based superconductors

Despite the fact that the Fe‐based superconductors (FeSCs) were discovered nearly 10 years ago, the community is still devoting a tremendous effort toward elucidating their relevant microscopic

Imaging orbital-selective quasiparticles in the Hund’s metal state of FeSe

Quasiparticle scattering interference resolved by orbital content reveals that orbital-selective strong correlations dominate the parent state of iron-based high-temperature superconductivity in FeSe, consistent with earlier orbitally selective Cooper pairing studies.



Z 2 -slave-spin theory for strongly correlated fermions

We review a representation of Hubbard-like models that is based on auxiliary pseudospin variables. These pseudospins refer to the local charge modulo two in the original model and display a local

Fermi-liquid, non-Fermi-liquid, and Mott phases in iron pnictides and cuprates

The role of Coulomb correlations in the iron pnictide LaFeAsO is studied by generalizing exact diagonalization dynamical mean field theory to five orbitals. For rotationally invariant Hund's rule

Orbital-selective Mott transition in multiband systems : Slave-spin representation and dynamical mean-field theory

We examine whether the Mott transition of a half-filled, two-orbital Hubbard model with unequal bandwidths occurs simultaneously for both bands or whether it is a two-stage process in which the

High-spin to low-spin and orbital polarization transitions in multiorbital Mott systems.

It is found that the Hund coupling can drive the system into a novel Mott insulating phase with vanishing orbital susceptibility, and away from half-filling, the crystal field splitting can induce an orbital selective Mott state.

Slave spins away from half filling: Cluster mean-field theory of the Hubbard and extended Hubbard models

A new slave-spin representation of fermion operators has recently been proposed for the half-filled Hubbard model. We show that with the addition of a gauge variable, the formalism can be extended to

Dynamical mean-field theory of strongly correlated fermion systems and the limit of infinite dimensions

We review the dynamical mean-field theory of strongly correlated electron systems which is based on a mapping of lattice models onto quantum impurity models subject to a self-consistency condition.

Selective Mott physics as a key to iron superconductors.

This scenario reconciles contrasting evidences on the electronic correlation strength, implies a strong asymmetry between hole and electron doping, and establishes a deep connection with the cuprates.

Mott transition at large orbital degeneracy: Dynamical mean-field theory

We study analytically the Mott transition of the N-orbital Hubbard model using dynamical mean-field theory and a low-energy projection onto an effective Kondo model. It is demonstrated that the

Weak and Strong Correlations in Fe Superconductors

In this chapter I will discuss the strength of electronic correlations in the normal phase of Fe-superconductors. It will be shown that the agreement between a wealth of experiments and DFT+DMFT or

Generalized slave-particle method for extended Hubbard models

We introduce a set of generalized slave-particle models for extended Hubbard models that treat localized electronic correlations using slave-boson decompositions. Our models automatically include two
