Paradigm for finding d-electron heavy fermions: the case of Cr-doped CsFeAs
Matteo Crispino, Pablo Villar Arribi, Anmol Shukla +8
We define a general strategy for finding new heavy-fermionic materials without rare-earth elements: doping a Hund metal with pronounced orbital-selective correlations towards half-…
Slave-spin mean field for broken-symmetry states: Néel antiferromagnetism and its phase separation in multi-orbital Hubbard models
Matteo Crispino, Maria Chatzieleftheriou, Tommaso Gorni +1
We introduce the generalization of the Slave-Spin Mean-Field method to broken-symmetry phases. Through a variational approach we derive the single-particle energy shift in the mean…
Linear behavior of the optical conductivity and incoherent charge transport in BaCoS2
D. Santos-Cottin, Y. Klein, Ph. Werner +5
Optical conductivity measurements on a BaCoS2 single crystal show an unusual linear behavior over a broad spectral range. In the paramagnetic phase above 300 K, the spectrum shows…
Mott transitions with partially-filled correlated orbitals
Adriano Amaricci, Luca de' Medici, Massimo Capone
We investigate the metal-insulator Mott transition in a generalized version of the periodic Anderson model, in which a band of itinerant electrons is hybridrized with a narrow and…
