Anizotropic Ising Model on 2D Kagom\'{e} Lattice as an Inhomogeneous XYZ Integrable Model

We investigate a generalized inhomogeneous two-dimensional Ising model on the kagom\'e lattice with two alternating couplings $J_i$ and $J'_i$, $i=1,2,3$, along the three lattice directions. The local Boltzmann weights are mapped onto a non-symmetric eight-vertex $R$-matrix satisfying the free-fermion condition for arb...
