Tunable Electronic Correlations in 135-Kagome Metals
Matteo Crispino, Niklas Witt, Stefan Enzner +4
Kagome metals exhibit rich correlated-electron physics, yet a systematic understanding of the degree of correlation across transition-metal species remains elusive. Using density-f…
Local-moment magnetism in Mn-based pnictides
Matteo Crispino, Niklas Witt, Tommaso Gorni +2
We report a comprehensive study of electronic-correlation effects in Manganese-based antiferromagnetic pnictides BaMnPn (Pn=P,As,Sb,Bi). Our density functional theory plus…
Hund flat band in a frustrated spinel oxide
Dongjin Oh, Alexander Hampel, Joshua P. Wakefield +26
Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenom…
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…
