Eight-vertex model and quantum XYZ model

introduction

• This model includes the dimer, ice and zero-field Ising, F and KDP models as special cases.
• Sutherland 1970 showed that any eight-vertex model transfer matrix commutes with an XYZ Hamiltonian
• Baxter considered (unaware of Sutherland 1970) the problem of the commutation of two eight-vertex transfer matrices

Hamiltonian

• XYZ Hamiltonian

\[\hat H = -\frac{1}{2} \sum_{j=1}^{N} (J_x \sigma_j^x \sigma_{j+1}^x + J_y \sigma_j^y \sigma_{j+1}^y + J_z \sigma_j^z \sigma_{j+1}^z - h\sigma_j^{z})\]
