Inelastic neutron scattering of the layered Kitaev ferromagnet Li $_{3}$ Co $_{2}$ SbO $_{6}$

Abdul Basit, Richard A. Mole, Alex J. Brown +3

Cobalt-based quantum magnets forming layered honeycomb arrangements have attracted much attention recently, as they are considered as a potential platform for materials with exotic…

Relevance of on-site and intersite Coulomb interactions in the Kitaev-Heisenberg magnet Na $_{3}$ Co $_{2}$ SbO $_{6}$

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…

Spin 3/2 dimer model

Stephan Rachel

We present a parent Hamiltonian for weakly dimerized valence bond solid states for arbitrary half-integral S. While the model reduces for S=1/2 to the Majumdar-Ghosh Hamiltonian we…
