Generic spin model for the honeycomb iridates beyond the Kitaev limit
Jeffrey G. Rau, Eric Kin-Ho Lee, Hae-Young Kee
Recently, realizations of Kitaev physics have been sought in the A2IrO3 family of honeycomb iridates, originating from oxygen-mediated exchange through edge-shared octahedra. Howev…
Order-by-disorder and magnetic field response in Heisenberg-Kitaev model on a hyperhoneycomb lattice
SungBin Lee, Eric Kin-Ho Lee, Arun Paramekanti +1
We study the finite temperature phase diagram of the Heisenberg-Kitaev model on a three dimensional hyperhoneycomb lattice. Using semiclassical analysis and classical Monte-Carlo s…
Heisenberg-Kitaev model on hyperhoneycomb lattice
Eric Kin-Ho Lee, Robert Schaffer, Subhro Bhattacharjee +1
Motivated by recent experiments on LiIrO, we study the phase diagram of the Heisenberg-Kitaev model on a three dimensional lattice of tri-coordinated Ir, dubbed…
