We show that the value of the spontaneous magnetization for the twodimensional Ising model computed by Onsager is indeed, the appropriate derivative of the free energy with respect to the magnetic field. The argument is based on a simple application of the duality transformation

Abstract
We show that the value of the spontaneous magnetization for the twodimensional Ising model computed by Onsager is indeed, the appropriate derivative of the free energy with respect to the magnetic field. The argument is based on a simple application of the duality transformationFile allegati a questo prodotto
