Название: Critical temperature for two-dimensional ising ferromagnets with quenched bond disorder
Автор: Fisch R.
Аннотация:
The configuration-averaged free energy of a quenched, random bond Ising model on a square lattice which contains an equal mixture of two types of ferromagnetic bonds J1 and J2 is shown to obey the same duality relation as the ordered rectangular model with the same two bond strengths.
