MEE denominates the mutual influence of the electric and magnetic properties in matter. In its most prominent form, MEE can be defined as the magnetic field dependence of (ferro)electric polarization and the electric field dependence of magnetization.
2d classical lattice models of statistical mechanics
Integrable quantum spinchains
Similar algebraic structure of 2d classical model and integrable quantum chainsR-matrix of Boltzmann weights
Commutativeity of the transfer-matrices
