Extent of frustration in the classical Kitaev-$\Gamma$ model via bond anisotropy

Ahmed Rayyan, Qiang Luo, Hae-Young Kee

In the pseudospin-$\frac{1}{2}$ honeycomb Mott insulators with strong spin-orbit coupling, there are two types of bond-dependent exchange interactions, named Kitaev ($K$) and $\Gamma$,…
