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…

Ground State Properties of the Doped Kitaev-Heisenberg Chain: Topological Superconducting and Mott Insulating Phases Driven by Magnetic Frustration
Cliò Efthimia Agrapidis, Satoshi Nishimoto
We study the hole-doped Kitaev-Heisenberg chain using the density-matrix renormalization group. In the Kitaev-only limit, the bond-directional exchange itself promotes pairing, fav…

Competing magnetic and topological orders in the spin-1 Kitaev-Heisenberg chain with single-ion anisotropy
Sahinur Reja, Satoshi Nishimoto
We investigate the ground-state phase diagram of the spin-1 Kitaev--Heisenberg chain in the presence of uniaxial single-ion anisotropy (SIA) by density-matrix renormalization…
