Challenges in design of Kitaev materials: Magnetic interactions from competing energy scales

SM Winter, Y Li, HO Jeschke, R Valentí - Physical Review B, 2016 - APS
In this study, we reanalyze the magnetic interactions in the Kitaev spin-liquid candidate

Strong correlations from Hund's coupling

A Georges, L Medici, J Mravlje - Annu. Rev. Condens. Matter …, 2013 - annualreviews.org
Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

Topotactic Hydrogen in Nickelate Superconductors and Akin Infinite-Layer Oxides

L Si, W Xiao, J Kaufmann, JM Tomczak, Y Lu, Z Zhong… - Physical review …, 2020 - APS
Superconducting nickelates appear to be difficult to synthesize. Since the chemical
reduction of ABO 3 [rare earth (A), transition metal (B)] with CaH 2 may result in both ABO 2 …

Selective Mott physics as a key to iron superconductors

L de'Medici, G Giovannetti, M Capone - Physical review letters, 2014 - APS
We show that electron-and hole-doped BaFe 2 As 2 are strongly influenced by a Mott
insulator that would be realized for half-filled conduction bands. Experiments show that …
