Near itinerancy and slow singlet formation in the triangular lattice NaRuO2
Charles C. Tam, Alon Hendler Avidor, Pritam Bhattacharyya +6
NaRuO forms a delafossite-like structure that contains triangular sublattices of edge-sharing RuO octahedra. It shows no evidence of magnetic order down to 100 mK and persi…
Physical properties of new delafossite triangular-lattice compounds TlErSe and TlTmSe
Bastian Rubrecht, Ellen Häußler, Mirtha Pillaca +7
Delafossite compounds containing rare-earth ions have been proven to be an ideal platform to investigate frustrated magnetic ground states. Here, we discuss two triangular-lattice…
More bridging ligands activate direct exchange: the case of anisotropic Kitaev effective magnetic interactions
Pritam Bhattacharyya, Nikolay A. Bogdanov, Liviu Hozoi
A magnet is a collection of magnetic moments. How those interact is determined by what lies in between. In transition-metal and rare-earth magnetic compounds, the configuration of…
Relevance of on-site and intersite Coulomb interactions in the Kitaev-Heisenberg magnet NaCoSbO
Pritam Bhattacharyya, Abdul Basit, Thorben Petersen +3
The detection of considerable spin frustration in honeycomb cobalt oxide compounds indicates the presence of sizable Kitaev interactions in these systems, enlarging the pool of Kit…
Fermiology of Cuprates from First Principles: From Small Pockets to the Luttinger Fermi surface
L. Hozoi, M. S. Laad, P. Fulde
Fermiology, the shape and size of the Fermi surface, underpins the low-temperature physical properties of a metal. Recent investigations of the Fermi surface of high-Tc superconduc…
Quasiparticle bands in cuprates by quantum chemical methods: towards an ab initio description of strong electron correlations
L. Hozoi, M. Laad
Realistic electronic-structure calculations for correlated Mott insulators are notoriously hard. Here we present an ab initio multiconfiguration scheme that adequately describes st…
