Tuning into the Kitaev spin liquid phase:A spin model on the honeycomb lattice with two types of Heisenberg exchange couplings

Yue Yu, Long Liang, Qian Niu +1

We study a spin model on honeycomb lattice with two types of Heisenberg exchange couplings, $J$ and $\tilde{J}$, where $J$ is for the conventional spin and and $\tilde{J}$ for rotate…
