Three solvable models are set out in some detail in reviewing different types of phase transitions. Two of these relate directly to emergent critical phenomena, viz. melting and magnetic transitions in heavy rare-earth metals, and secondly, via the 3d Ising model, to critical behavior in an insulating ferromagnet such as CrBr3. The final "transition", however, concerns ionization of an electron in an isoelectronic series with N electrons as the atomic number Z is reduced below that of the neutral atom. These solvable models are, throughout, brought into contact either with experiment, or with very precise numerical modeling on real materials.

Abstract
Three solvable models are set out in some detail in reviewing different types of phase transitions. Two of these relate directly to emergent critical phenomena, viz. melting and magnetic transitions in heavy rare-earth metals, and secondly, via the 3d Ising model, to critical behavior in an insulating ferromagnet such as CrBr3. The final "transition", however, concerns ionization of an electron in an isoelectronic series with N electrons as the atomic number Z is reduced below that of the neutral atom. These solvable models are, throughout, brought into contact either with experiment, or with very precise numerical modeling on real materials.File | Dimensione | Formato | |
